Hmmm.

id Tech is supposed to release the source code for the 3D engine "id Tech 4" this year around August/September. Now its based on C++ and OpenGL and has many complex features (MegaTexture).

This is basically what's needed to make your very own FPS/Third-Person-Shooter ... or simulator applications such as somethingTycoon, Engineering Project etc.

I believe this will innovate the gaming field late this year and early next year. Because talented developers/groups will bring Linux (Debian, Fedora, etc) one step closer to current-gen in graphics rendering, and I expect Maemo(this community), Android, WebOS, QNX (?) and possibly MeeGo to be involved aswell.

And you thought Infinity Blade looked good?
