List of JS game engines. You can find a wikified version at https://github.com/bebraw/jswiki/wiki/Game-Engines. Feel free to modify that. I sync it here every once in a while.

IMPORTANT! Remember to check out the wiki page at https://github.com/bebraw/jswiki/wiki/Game-Engines for the most up to date version. There's also a "notes" column in the table but it simply does not fit there... Check out the raw version to see it.

This table contains primarily HTML5 based game engines and frameworks. You might also want to check out the [[Feature Matrix|Game-Engine-Feature-Matrix]], [[Game Resources]] and [[Scene Graphs]].
