I haven't played most of these games, but I might still be able to give you some good advice.
DOAU
- I don't have it yet, but I have the original versions and those were excellent
Burnout 3: Takedown
- I wouldn't know anything about this, I hate EA Games
Capcom vs. SNK 2 EO
- Decent 2D fighter, definitely worth the money this usually costs
Sega GT Online
- I heard that the online game sucks, you're probably better of getting the Sega GT 2002/JSRF combo disc instead
Tom Clancy's Ghost Recon⢠2
- A solid tactical shooter based on what I've seen so far
TRON 2.0®: KILLER APP
-
If you're looking for a good cheap FPS get TimeSplitters 2 or Halo instead
MechAssault
- I'm not a big fan of the multiplayer deathmatch thing, but if you're into that this is a good game. Try and kill two birds with one stone and get the Xbox Live kit that is bundled with MechAssault
