usually on cod 4 and 5. usually hardcore team deathmatch or sabotage.
used to play forza 2 but got mad at it one night and never played it again! might give another go soon though.
I have a jdm style Crx in black with red work Emotion wheels. fully tuned to over 500bhp, and you can properly hear the vtec on forza 2, its brilliant game.
