Quake, Free and Clear

One of my favorite things about id is Carmack's ongoing efforts to release all their old code under GPL. According to blues, he just accounced at QuakeCon that Q3A will be GPL shortly, making everything pre-Trinity .. er Doom 3 ... open to the public.

That just rocks. Blues even points to the release of Silver Wings, pictured to the right there, a Quake I based arcade style shooter. And of course the Quake II engine has been used for projects like UFO: Alien Invasion (and inspired by X-Com). The wealth of technology this shares with community (and by the terms of the GPL ... keeps on sharing) is immense.
