Editing D20 System (section)

== Controversy ==
When gaming company Valar Project attempted to publish the d20 ''Book of Erotic Fantasy'' (''BoEF''), which focused on sexual content, Wizards of the Coast altered the d20 System Trademark License in advance of publication of ''BoEF'' by adding a "quality standards" provision that required publishers to comply with "community standards of decency." This subsequently prevented the book's publication under the d20STL.<ref>{{Cite web |date=20 November 2003 |title=Book of Erotic Fantasy Loses d20 License |url=http://www.gamingreport.com/article.php?sid=10243&mode=thread |url-status=dead |archive-url=https://web.archive.org/web/20031120193937/http://www.gamingreport.com/article.php?sid=10243&mode=thread |archive-date=20 November 2003 |access-date=26 January 2018 |website=GamingReport.com}}</ref> Wizards of the Coast said this was done to protect its d20 System trademark. The ''Book of Erotic Fantasy'' was subsequently published without the d20 System trademark under the OGL. Other books subsequently published under similar circumstances include [[Skirmisher Publishing]]'s ''Nuisances'', which includes on its cover the disclaimer "Warning: intended for mature readers only."

The same round of changes to the license also limited the size at which the text "Requires the use of the ''Dungeons & Dragons Player's Handbook'', Third Edition, published by Wizards of the Coast" (which is required to appear on the front or back cover of most fantasy d20 System products) could be printed, and prohibited making part of it larger than the rest.
