A '''game engine''' is a [[software framework]] primarily designed for the development of [[video game]]s which generally includes relevant [[library (computing)|libraries]] and support programs such as a level editor.<ref>{{cite book|url=https://books.google.com/books?id=bZZyDQAAQBAJ&pg=PA146 |title=Technologies and Innovation: Second International Conference, CITI 2016, Guayaquil, Ecuador, November 23-25, 2016, Proceedings |isbn=9783319480244 |access-date=2021-07-22 |last1=Valencia-Garcia |first1=Rafael |display-authors=et al. |year=2016|publisher=Springer }}</ref> The "engine" terminology is akin to the term "[[software engine]]" used more widely in the [[software industry]].

''Game engine'' can also refer to the development software supporting this framework, typically a suite of tools and features for developing games.<ref>{{cite web |url=https://unity.com/how-to/beginner/game-development-terms |title=Common game development terms and definitions &#124; Game design vocabulary &#124; Unity |publisher=Unity |access-date=2021-07-14 |archive-url=https://web.archive.org/web/20170806002513/https://cdn2.unrealengine.com/Resources/files/Build_1.x_Not_1.0_JamesTan-1535398852.pdf |archive-date=2017-08-06 |url-status=live}}</ref><ref>{{cite web |url=https://cdn2.unrealengine.com/Resources/files/Build_1.x_Not_1.0_JamesTan-1535398852.pdf |title=Introduction - Unreal Engine (Canterbury Software Summit 2013 slides) |last=Tan |first=James |website= Unreal Engine |access-date=2021-07-14}}</ref>

[[Video game developer|Developers]] can use game engines to construct games for [[video game console]]s and other types of [[computer]]s. The core functionality typically provided by a game engine may include a [[rendering (computer graphics)|rendering]] engine ("renderer") for [[2D computer graphics|2D]] or [[3D computer graphics|3D]] [[computer graphics|graphics]], a [[physics engine]] or [[collision detection]] (and collision response), [[sound]], [[scripting language|scripting]], [[computer animation|animation]], [[game AI|artificial intelligence]], [[computer networking|networking]], streaming, [[memory management]], [[thread (computing)|threading]], [[internationalization and localization|localization]] support, [[scene graph]], and video support for [[cinematic cutscene|cinematics]]. Game engine implementers often economize on the process of [[game development]] by reusing/adapting, in large part, the same game engine to produce different games<ref>
