Xbox live games
Crimson Skies
Mech Assault
Brute Force
Burnout 2(although the only thing this game tracks on line is your score, no head to head gaming 

)
Midtown Madness 3 
Might go out and buy Van Helsing, looks like it might be fun. 
Future purchases
Halo2 (well, thats IF Microsoft ever gives it to us) 
Dead or Alive Ultimate(no, I just buy the game because I like the action, it has nothing to do whether "she kicks high" 

 )
