I'm not a gamer, but I thought I'd poke around and see what the game status was on Linux. It's not as dire as some claim... :)
A nice site with GNU/Linux game info:
Some games that you can get from the BLAG repository:
tuxracer <--- race down a hill & eat herring
wesnoth <---- strategy game http://www.wesnoth.org/
torcs <--- car racing game.
apt-get install tuxracer
apt-get install wesnoth
apt-get install torcs-data-cars-extra torcs-data-cars-nascar torc-data-tracks-oval torcs-robots torcs-data-tracks-road
I'll keep hunting around & adding to this list.
You could also check out freeciv, but I don't really understand it.
apt-get install freeciv
civserver (not as root)
Other apt-gettable games that people like are bzflag, supertux, & neverball.
Flight simulator (not in repository, but I think it's coming soon--looks very good):http://flightgear.org/
A huge game with lots of players & pretty complex is Planeshift:http://www.planeshift.it/
This looks kinda cool, but I didn't play with it much:http://www.ufoai.net/
Some binary-only, but free games:
wolfenstein: http://games.activision.com/games/wolfe ... section=et
Also, you can run a lot of MS games using wine.
apt-get install wine
Games on linux, but cost $:
Not sure if they are free or not (exactly), but you get source & then run on linux:
Quake 2: http://www.idsoftware.com/games/quake/quake2/
