The rapid availability of the Internet in the 1990s led to an expansion of online games, with notable titles including ''[[Nexus: The Kingdom of the Winds]]'' (1996), ''[[Quakeworld]]'' (1996), ''[[Ultima Online]]'' (1997), ''[[Lineage (computer game)|Lineage]]'' (1998), ''[[StarCraft]]'' (1998), ''[[Counter-Strike]]'' (1999) and ''[[EverQuest]]'' (1999).

=== Console gaming ===
{{Main|Xbox Live|PlayStation Network|Nintendo Switch Online}}
[[Xbox Live]] was launched in November 2002. Initially the console only used a feature called system link, where players could connect two consoles using an [[Ethernet physical layer|Ethernet cable]], or multiple consoles through a router. With the original Xbox Microsoft launched Xbox Live, allowing shared play over the internet. A similar feature exists on the [[PlayStation 3]] in the form of the [[PlayStation Network]], and the [[Wii]] also supports a limited amount of online gaming. Nintendo also had a network, dubbed "[[Nintendo Network]]", that fully supported online gaming with the [[Wii U]] and [[Nintendo 3DS]]. With the launch of the [[Nintendo Switch]], Nintendo launched the [[Nintendo Switch Online]] service to replace the older Nintendo Network.

As the [[World Wide Web]] developed and browsers became more sophisticated, people started creating [[browser game]]s that used a [[web browser]] as a client. Simple single player games were made that could be played using a web browser (most commonly made with web technologies like [[HTML]], [[JavaScript]], [[Active Server Pages|ASP]], [[PHP]] and [[MySQL]]).

The development of web-based graphics technologies such as [[Adobe Flash|Flash]] and [[Java (programming language)|Java]] allowed browser games to become more complex. These games, also known by their related technology as "[[Browser game|Flash games]]" or "Java games", became increasingly popular. Games ranged from simple concepts to large-scale games, some of which were later released on consoles. Many Java or Flash games were shared on various different websites, bringing them to wide audiences.<ref>{{Cite magazine |last=Reeves |first=Ben |title=How Flash Games Changed Video Game History |url=https://www.gameinformer.com/2018/12/22/how-flash-games-changed-video-game-history |archive-url=https://web.archive.org/web/20181226024524/https://www.gameinformer.com/2018/12/22/how-flash-games-changed-video-game-history |url-status=live |archive-date=December 26, 2018 |access-date=April 15, 2022 |magazine=Game Informer |language=en}}</ref> Browser-based pet games are popular among the younger generation of online gamers. These games range from gigantic games with millions of users, such as ''[[Neopets]]'', to smaller and more community-based pet games.

More recent browser-based games use web technologies like [[Ajax (programming)|Ajax]] to make more complicated multiplayer interactions possible and [[WebGL]] to generate hardware-accelerated 3D graphics without the need for plugins.

== Types of interactions ==
===Player versus environment (PvE)===
{{Main|Player versus environment}}
PvE is a term used in online games, particularly MMORPGs and other role-playing video games, to refer to fighting computer-controlled opponents.

===Player versus player (PvP)===
{{Main|Player versus player}}
PvP is a term broadly used to describe any game, or aspect of a game, where players compete against each other rather than against computer-controlled opponents.

==Online games==
===First-person shooter game (FPS)===
{{Main|First-person shooter}}
During the 1990s, online games started to move from a wide variety of [[Local area network|LAN]] protocols (such as [[Internetwork Packet Exchange|IPX]]) and onto the Internet using the [[Internet protocol suite|TCP/IP]] protocol. ''[[Doom (1993 video game)|Doom]]'' popularized the concept of a [[deathmatch (video games)|deathmatch]], where multiple players battle each other head-to-head, as a new form of online game. Since Doom, many first-person shooter games contain online components to allow deathmatch or arena style play. And by popularity, first person shooter games are becoming more and more widespread around the world. As games became more realistic and competitive, an e-sports community was born. Games like ''[[Counter-Strike]]'', ''[[Halo (series)|Halo]]'', ''[[Call of Duty (series)|Call of Duty]]'', ''[[Quake Live]]'' and ''[[Unreal Tournament]]'' are popular with these tournaments''.'' These tournaments have a range of winnings from money to hardware.

Expansion of [[hero shooter]]s, a sub-genre of [[shooter game]]s, happened in 2016 when several [[video game developer|developers]] released or announced their hero shooter [[multiplayer online game]]. Hero shooters have been considered to have strong potential as an esport, as a large degree of skill and coordination arises from the importance of teamwork. Some notable examples include ''[[Battleborn (video game)|Battleborn]]'', ''[[Overwatch (video game)|Overwatch]]'', ''[[Paladins: Champions of the Realm|Paladins]]'' and ''[[Valorant]]''.<ref>{{cite web | url = http://www.gamasutra.com/view/news/271933/Hero_Shooters_Charting_the_rebirth_of_a_genre.php | title = Hero Shooters: Charting the (re)birth of a genre | work = [[Gamasutra]] | date = May 6, 2016 | access-date = May 6, 2016 | first = Alex | last = Wawro | archive-date = May 7, 2016 | archive-url = https://web.archive.org/web/20160507142751/http://www.gamasutra.com/view/news/271933/Hero_Shooters_Charting_the_rebirth_of_a_genre.php | url-status = dead }}</ref>

===Real-time strategy game (RTS)===
{{Main|Real-time strategy}}
Early [[real-time strategy]] games often allowed multiplayer play over a modem or local network.<ref name="Rollings"/> As the Internet started to grow during the 1990s, software was developed that would allow players to tunnel the LAN protocols used by the games over the Internet. By the late 1990s, most RTS games had native Internet support, allowing players from all over the globe to play with each other.<ref name="Rollings">{{cite book |last=Rollings |first=Andrew |author2=Ernest Adams |title=Andrew Rollings and Ernest Adams on Game Design |publisher=New Riders Publishing |year=2003 |pages=290–296 |url=http://my.safaribooksonline.com/1592730019/ch09?portal=adobepress#ch09 |access-date=April 25, 2018 |archive-date=March 31, 2017 |archive-url=https://web.archive.org/web/20170331161214/http://my.safaribooksonline.com/1592730019/ch09?portal=adobepress#ch09 |url-status=dead }}</ref> Popular RTS games with online communities have included ''[[Age of Empires (series)|Age of Empires]]'', ''[[Sins of a Solar Empire]]'', ''[[StarCraft (series)|StarCraft]]'' and ''[[Warhammer 40,000: Dawn of War]]''.

===Massively multiplayer online game (MMO)===
{{Main|Massively multiplayer online game}}
[[Massively multiplayer online game]]s were made possible with the growth of [[Internet access|broadband Internet access]] in many developed countries, using the Internet to allow hundreds of thousands of players to play the same game together. Many different styles of massively multiplayer games are available, such as:
*[[Massively multiplayer online role-playing game|MMORPG]] (Massively multiplayer online [[role-playing game]])
*[[Massively multiplayer online game#Real-time strategy|MMORTS]] (Massively multiplayer online [[real-time strategy]])
*[[Massively multiplayer online game#First-person shooter|MMOFPS]] (Massively multiplayer online [[first-person shooter]])
*[[Massively multiplayer online game#Social|MMOSG]] (Massively multiplayer online social game)

===Multiplayer online battle arena game (MOBA)===
{{Main|Multiplayer online battle arena}}
A specific subgenre of [[strategy video game]]s referred to as [[multiplayer online battle arena]] (MOBA) gained popularity in the 2010s as a form of [[electronic sports]], encompassing games such as the ''[[Defense of the Ancients]]'' mod for ''[[Warcraft III]]'', ''[[League of Legends]]'', ''[[Dota 2]]'', ''[[Smite (video game)|Smite]],'' and ''[[Heroes of the Storm]].''<ref>{{Cite web|url=https://www.progamerreview.com/best-moba-games/|title=Best Modern MOBA Games - LoL, Dota 2, HotS & Smite Compared|last1=Amstrup|first1=Johannes|last2=ersen|date=September 15, 2017|website=Pro Gamer Reviews|language=en-US|access-date=October 19, 2019|archive-date=October 19, 2019|archive-url=https://web.archive.org/web/20191019134555/https://www.progamerreview.com/best-moba-games/|url-status=live}}</ref> Major esports professional tournaments are held in venues that can hold tens of thousands of spectators and are streamed online to millions more.<ref>{{Cite web|agency=Agence France-Presse|date=November 5, 2017|title=Video game warriors do battle before 40,000 fans in China|url=https://technology.inquirer.net/68752/technology-games-china-video-games-esports-league-of-legends-birds-nest|access-date=July 19, 2020|website=INQUIRER.net|language=en|archive-date=July 18, 2020|archive-url=https://web.archive.org/web/20200718012132/https://technology.inquirer.net/68752/technology-games-china-video-games-esports-league-of-legends-birds-nest|url-status=live}}</ref><ref>{{Cite web|last=Webb|first=Kevin|title=More than 100 million people watched the 'League of Legends' World Championship, cementing its place as the most popular esport|url=https://www.businessinsider.com/league-of-legends-world-championship-100-million-viewers-2019-12|access-date=July 19, 2020|website=Business Insider|archive-date=January 31, 2021|archive-url=https://web.archive.org/web/20210131115618/https://www.businessinsider.com/league-of-legends-world-championship-100-million-viewers-2019-12|url-status=live}}</ref><ref>{{Cite web|last=Boudreau|first=Ian|date=August 26, 2019|title=The International 2019 was Twitch's most-watched Dota 2 event ever|url=https://www.pcgamer.com/the-international-2019-was-twitchs-most-watched-dota-2-event-ever/|access-date=July 19, 2020|website=PC Gamer|language=en-US|archive-date=March 9, 2021|archive-url=https://web.archive.org/web/20210309234029/https://www.pcgamer.com/the-international-2019-was-twitchs-most-watched-dota-2-event-ever/|url-status=live}}</ref> A strong fanbase has opened up the opportunity for sponsorship and advertising, eventually leading the genre to become a global cultural phenomenon.<ref name=":1" /><ref>{{Cite web|last=Meola|first=Andrew|title=The biggest companies sponsoring eSports teams and tournaments|url=https://www.businessinsider.com/top-esports-sponsors-gaming-sponsorships-2018-1|access-date=September 25, 2020|website=Business Insider|archive-date=September 19, 2020|archive-url=https://web.archive.org/web/20200919172022/https://www.businessinsider.com/top-esports-sponsors-gaming-sponsorships-2018-1|url-status=live}}</ref>

===Battle Royale games===
{{Main|Battle royale game}}
A battle royale game is a genre that blends the survival, exploration and scavenging elements of a [[survival game]] with [[Last man standing (gaming)|last-man-standing]] gameplay. Dozens to hundreds of players are involved in each match, with the winner being the last player or team alive. Some notable examples include ''[[PlayerUnknown's Battlegrounds]]'', ''[[Fortnite Battle Royale]]'', ''[[Apex Legends]],'' and ''[[Call of Duty: Warzone]],'' each having received tens of millions of players within months of their releases.<ref>{{Cite web|url=https://www.pcgamer.com/how-battle-royale-changed-the-last-decade-of-games-and-the-next-one/|title=How battle royale changed the last decade of games (and the next one)|last=Livingston|first=Christopher|date=December 11, 2019|website=PC Gamer|language=en-US|access-date=January 9, 2020|archive-date=December 4, 2021|archive-url=https://web.archive.org/web/20211204043253/https://www.pcgamer.com/how-battle-royale-changed-the-last-decade-of-games-and-the-next-one/|url-status=live}}</ref><ref name=":0">{{Cite web|url=https://www.polygon.com/2020/4/10/21216734/call-of-duty-warzone-50-million-player-count|title=Call of Duty: Warzone hits 50M players in first month|last=McWhertor|first=Michael|date=April 10, 2020|website=Polygon|language=en|access-date=April 21, 2020|archive-date=April 20, 2020|archive-url=https://web.archive.org/web/20200420145529/https://www.polygon.com/2020/4/10/21216734/call-of-duty-warzone-50-million-player-count|url-status=live}}</ref> The genre is designed exclusively for multiplayer gameplay over the Internet.

===MUD===
{{Main|Multi-user dungeon}}
MUD is a class of multi-user real-time virtual worlds, usually but not exclusively text-based, with a history extending back to the creation of ''[[MUD1]]'' by [[Richard Bartle]] in 1978. MUD were the direct predecessors of [[Massively multiplayer online role-playing game|MMORPG]].<ref>{{cite book| last = Castronova| first = Edward| author-link = Edward Castronova| title = Synthetic Worlds: The Business and Culture of Online Games| publisher = University Of Chicago Press| year = 2006| isbn = 978-0-226-09627-8| pages = [https://archive.org/details/syntheticworlds00edwa/page/10 10, 291]| quote = [pp. 10] The ancestors of MMORPG were text-based multiuser domains (MUD) [...] [pp. 291] Indeed, MUD generate perhaps the one historical connection between game-based VR and the traditional program [...]| url = https://archive.org/details/syntheticworlds00edwa/page/10}}</ref>

=== Other notable games ===
A [[social deduction game]] is a multiplayer online game in which players attempt to uncover each other's hidden role or team allegiance using logic and deductive reasoning, while other players can bluff to keep players from suspecting them. A notable example of the social deduction video game is ''[[Among Us]],'' which received a massive influx of popularity in 2020 due to many well-known [[Twitch (service)|Twitch]] [[Online streamer|streamers]] and [[YouTuber]]s playing it.<ref name=":2" /> ''Among Us'' has also inspired [[internet meme]]s and achieved a very large following online.<ref>{{Cite web|last=Marshall|first=Cass|date=September 11, 2020|title=Why Among Us' Emergency Meeting is the big social media mood|url=https://www.polygon.com/2020/9/11/21432684/among-us-emergency-meeting-meme-explained|access-date=July 12, 2021|website=Polygon|language=en|archive-date=September 21, 2020|archive-url=https://web.archive.org/web/20200921123243/https://www.polygon.com/2020/9/11/21432684/among-us-emergency-meeting-meme-explained|url-status=live}}</ref>

==Online game governance==
Online gamers must agree to an [[End-user license agreement]] (EULA) when they first install the game application or an update. EULA is a legal contract between the producer or distributor and the [[end-user]] of an application or software, which is to prevent the program from being copied, redistributed or hacked.<ref>{{cite web|last1=Nahmias|first1=Jordan|title=The EULA: What it does, how it works (and, what does EULA even mean)|url=http://www.nahmiaslaw.com/the-eula-what-it-does-how-it-works-and-what-does-eula-even-mean/|website=nahmiaslaw|access-date=May 14, 2015|archive-date=May 24, 2015|archive-url=https://web.archive.org/web/20150524114203/http://www.nahmiaslaw.com/the-eula-what-it-does-how-it-works-and-what-does-eula-even-mean/|url-status=live}}</ref> The consequences of breaking the agreement vary according to the contract. Players could receive warnings to termination, or direct termination without warning. In the 3D immersive world ''[[Second Life]]'' where a breach of contract will append the player warnings, suspension and termination depending on the offense.<ref>{{cite web|url=http://secondlife.com/community/blotter.php|archive-url=https://web.archive.org/web/20080820115258/http://secondlife.com/community/blotter.php |archive-date=August 20, 2008 |title=Community: Incident Report |publisher=Second Life |access-date=February 12, 2010}}</ref>

Where online games supports an in-game chat feature, it is not uncommon to encounter [[hate speech]], [[sexual harassment]] and [[cyberbullying]].<ref name=SRK>{{cite web|title=Back to Basics, Getting Beyond the Drama|url=http://shoryuken.com/2012/02/29/back-to-basics-getting-beyond-the-drama/|archive-url=https://archive.today/20130202074242/http://shoryuken.com/2012/02/29/back-to-basics-getting-beyond-the-drama/|url-status=dead|archive-date=February 2, 2013|publisher=shoryuken.com/|access-date=August 2, 2012|author=Inkblot|date=February 29, 2012}}</ref><ref name=NYT8212>{{cite news|title=In Virtual Play, Sex Harassment Is All Too Real|url=https://www.nytimes.com/2012/08/02/us/sexual-harassment-in-online-gaming-stirs-anger.html|access-date=August 2, 2012|newspaper=The New York Times|date=August 1, 2012|author=Amy O'Leary|archive-date=March 9, 2017|archive-url=https://web.archive.org/web/20170309213932/http://www.nytimes.com/2012/08/02/us/sexual-harassment-in-online-gaming-stirs-anger.html|url-status=live}}</ref> Players, developers, gaming companies, and professional observers are discussing and developing tools which discourage [[Anti-social behaviour|antisocial behavior]].<ref name=ECH>{{cite web|title=Extra Credits: Harassment|url=https://www.youtube.com/watch?v=Dt9GwmOWoqo|first=James|last=Portnow| date=May 20, 2012 |publisher=Extra Credits|access-date=August 2, 2012|location=penny-arcade.com|format=video|quote=This week, we tackle the rampant bullying, misogyny and hate speech that occurs within the gaming community.|archive-date=July 7, 2012|archive-url=https://web.archive.org/web/20120707164012/http://www.youtube.com/watch?v=Dt9GwmOWoqo&gl=US&hl=en|url-status=live}} [http://penny-arcade.com/patv/episode/harassment Alt URL] {{Webarchive|url=https://web.archive.org/web/20131113021402/http://penny-arcade.com/patv/episode/harassment |date=November 13, 2013 }}</ref>
There are also sometimes [[Gamemaster|Moderators]] present, who attempt to prevent anti-Social behavior. Online games also often involve real-life illegal behavior, such as scam, financial crimes, invasion of privacy, and other issues.<ref>{{cite web|title=Fraud in the Online Gaming Industry|date=November 5, 2020 |url=https://isacybersecurity.com/fraud-in-the-online-gaming-industry/}}</ref><ref>{{cite web|title=Hate is No Game: Harassment and Positive Social Experiences in Online Games 2021|url=https://www.adl.org/resources/report/hate-no-game-harassment-and-positive-social-experiences-online-games-2021}}</ref><ref>{{cite web|title=The Potential Perils of Online Gaming|date=June 8, 2023 |url=https://www.acamstoday.org/the-potential-perils-of-online-gaming/}}</ref>

Recent development of gaming governance requires all video games (including online games) to hold a rating label. The voluntary rating system was established by the [[Entertainment Software Rating Board]] (ESRB). A scale can range from "E" (stands for Everyone) inferring games that are suitable for both children and adults, to "M" (stands for Mature) recommending games that are restricted to age above 17. Some explicit online games can be rated "AO" (stands for Adult Only), identifying games that have content suitable for only adults over the age of 18.  Furthermore, online games must also carry an ESRB notice that warns that any "online interactions are not rated by the ESRB".

==Shutdown of games==
The [[video game industry]] is highly competitive. As a result, many online games end up not generating enough profits, such that the service providers do not have the incentives to continue running the [[Server (computing)|servers]]. In such cases, the developers of a game might decide to shut down the server permanently.

Shutting down an online game can severely impact the players. Typically, a server shutdown means players will no longer be able to play the game. For many players, this can cause a sense of loss at an emotional level, since they often dedicate time and effort to making in-game progress, e.g., completing in-game tasks to earn [[Item (game terminology)|items]] for their characters. In some other cases, the game might still be playable without the server, but certain important functionalities will be lost. For example, earning key in-game items often requires a server that can track each player's progress.<ref>{{Cite web|date=2022-04-26|title=Ubisoft has officially shut down online services for over 90 games|url=https://www.videogameschronicle.com/news/ubisoft-has-officially-shut-down-online-services-for-over-90-games/|access-date=2023-02-17|website=VGC|language=en-GB|archive-date=June 25, 2022|archive-url=https://web.archive.org/web/20220625061623/https://www.videogameschronicle.com/news/ubisoft-has-officially-shut-down-online-services-for-over-90-games/|url-status=live}}</ref>

In some cases, an online game may be relaunched in a substantially different form after shutting down, in an attempt to increase the game's quality, remedy low sales, or reverse a declining player base, and see significantly greater success. [[Final Fantasy XIV (2010 video game)|''Final Fantasy XIV'']] was negatively received upon its 2010 release, and relaunched as ''[[Final Fantasy XIV|A Realm Reborn]]'' in 2013 - the new version was met with considerable positive reception, and is still running as of 2022.<ref>{{Cite web|author1=Leon Hurley|date=2015-04-16|title=7 online worlds that ended while people were still playing|url=https://www.gamesradar.com/7-games-shut-down-while-people-were-still-playing/|access-date=2023-02-17|website=gamesradar|language=en|archive-date=February 17, 2023|archive-url=https://web.archive.org/web/20230217104150/https://www.gamesradar.com/7-games-shut-down-while-people-were-still-playing/|url-status=live}}</ref> ''Splitgate: Arena Warfare'' relaunched as ''[[Splitgate]]'' in 2021, switching to a [[free-to-play]] model and adding cross-platform multiplayer, and subsequently saw 2 million new players, with the servers being unable to handle the influx.<ref>{{Cite web |date=July 26, 2021 |title=Splitgate won't launch into 1.0 until August as 1047 Games deals with servers |url=https://venturebeat.com/2021/07/26/splitgate-wont-launch-into-1-0-until-august-as-1047-games-deals-with-servers/ |access-date=June 30, 2022 |website=VentureBeat |language=en-US |archive-date=June 30, 2022 |archive-url=https://web.archive.org/web/20220630060823/https://venturebeat.com/2021/07/26/splitgate-wont-launch-into-1-0-until-august-as-1047-games-deals-with-servers/ |url-status=live }}</ref>

However, games may remain a [[commercial failure]] despite a planned relaunch. These include the 2015 asymmetrical [[first-person shooter]] ''[[Evolve (video game)|Evolve]]'', which transitioned to a free-to-play title known as ''Evolve Stage 2'' a year after launch, after it was criticized for its significant amount of [[Downloadable content|DLC]] despite being a full-priced game, but had its servers permanently shut down roughly two years later after its user base "evaporated" as a result of infrequent updates.<ref>{{Cite news |last=Wood |first=Austin |date=June 5, 2018 |title=Evolve dev says '4v1 caused more problems than we ever imagined' |language=en |work=[[PC Gamer]] |url=https://www.pcgamer.com/evolve-dev-says-4v1-caused-more-problems-than-we-ever-imagined/ |access-date=June 28, 2022 |archive-date=June 28, 2022 |archive-url=https://web.archive.org/web/20220628091228/https://www.pcgamer.com/evolve-dev-says-4v1-caused-more-problems-than-we-ever-imagined/ |url-status=live }}</ref> The 2019 looter-shooter ''[[Anthem (video game)|Anthem]]'' was also planned to be relaunched as ''Anthem Next'', but the changes were never implemented, partially due to the [[Impact of the COVID-19 pandemic on the video game industry|impact of the COVID-19 pandemic]] and an unwillingness to further invest in the game by ''[[Electronic Arts]]''.<ref>{{Cite magazine |last=Juba |first=Joe |date=February 24, 2021 |title=Anthem 2.0 Canceled By BioWare |url=https://www.gameinformer.com/2021/02/24/anthem-20-canceled-by-bioware |archive-url=https://archive.today/20221024011747/https://www.gameinformer.com/2021/02/24/anthem-20-canceled-by-bioware |url-status=live |archive-date=October 24, 2022 |access-date=June 28, 2022 |magazine=[[Game Informer]] |language=en}}</ref>
