Hi,

As I play mostly open source games since years I thought I provide a listing of what I think has good quality and s fun to play. Some are not 100% complete yet but make fun to play, so I listed them as well.
The source for finding opensource or linux games in general I like and use most is www.happypenguin.org, it contains a massive database of games running on linux that were created or released the last ten years. If you know more really good open source games then let me please know.

I'll complete the list with more games as soon as more come to my mind: The descriptions are taken from the home pages or happypenguin. I'll try to build the non 3d games myelf and will let you know if I succeed, for the 3D games it might make sense to contact the author if he is willing to help with a port as there is some patching necessary in order to get openGL games to run with openGLes if I understand correctly. Does anyone know of a good guide on this topic, then I'd also give it a shot.

edit: a introduction to porting to openGLes 2.0 can be found here:

http://wiki.maemo.org/OpenGL-ES

Impressive list, I haven't heard about SoulFu and looks very well.
