I've been on this free game kick -- and why not, with such a bad economy?

Here are some great free alternatives to the mainstream gaming market:
1. Cube 2 Sauerbraten - FPS
[http://sauerbraten.org/]
A free FPS with great graphics and a really fast-paced game play that takes some getting used to.
-----
2. Trackmania Nations Forever - Racing
]TrackMania - Home]
Great graphics, and is REALLY fun to play both online and off. Crazy tracks, and insane physics. One of the best racing games ever, and it's free!
-----
3. ZEQ2-LITE BETA - Free range DBZ fighting game
zeq2.com/lite
This is a DBZ game with free roam and huge maps, where you can fly around and unleash various attacks from a distance or up close melee style... it's a quick download and is pretty fun if you can find an online server (check the chatroom on the website)

4. Requiem - MMORPG
[www.playrequiem.com]
A pretty fun, free, and good looking "horror" MMORPG
-----
5. Grand Theft Auto 1 and 2
[http://www.rockstargames.com/classics/]
Classic GTA games, but free. The graphics are outdated, but still fun!
