However, releasing the source code may and has led to clones using the original proprietary assets from the game, with two notable examples of games having clones thanks to the source release being Canabalt and Lugaru HD.

Wolfire Games also noted (along with Saltsman) that releasing the source code didn't reduce sales. Some developers that have released their source code have concluded that, in general terms, such action has not been harmful and even beneficial, among them Alec Holowka ( Aquaria), Adam Saltsman ( Canabalt), John Carmack ( Wolfenstein 3D, Doom, Quake), Brian Hook ( Quake II), and Terry Cavanagh ( VVVVVV). with unofficial patches to fix bugs or source ports to make the game compatible with new platforms.

Source code availability in whatever form allows the games' communities to study how the game works, make modifications, and provide technical support themselves when the official support has ended, e.g. SourceForge or GitHub), or given to selected game community members, or sold with the game, or become available by other means. The source code may be pushed by the developers to public repositories (e.g. Such source code is often released under varying (free and non-free, commercial and non-commercial) software licenses to the games' communities or the public artwork and data are often released under a different license than the source code, as the copyright situation is different or more complicated. In several of the cases listed here, the game's developers released the source code expressly to prevent their work from becoming abandonware. When there is no more expected revenue, these games enter the end-of-life as a product with no support or availability for the game's users and community, becoming abandoned.
