W00t, tremulous uses my Quake 3 engine:

Savage? Long lost? The game is on the developer's website free and Savage 2 is out soon.

Open source, free, and it runs on Linux? excelent :D

Just downloaded it a few minutes ago...looks pretty cool, but I didn't see anyone playing it. Another really cool Quake3-engine based project I've been fooling around with is called OpenArena. It's still very early and in alpha, but looks promising: http://cheapy.deathmask.net/

I am in favor of goons.

Temulous is popular among Something Awful goons since the developers are goons. What's most interesting is the fact that it was built off the Quake 3 open source engine, so it's less of a mod and more of an independent-dev-using-popular-engine game. Or something like that.

It's like Natural Selection, without needing to have Half-Life. :-P

Best Quote Evar.

Sounds almost like Enemy Territory... man I loved that game.
