yay! I have Micro Machines V3 too!
At first I got pretty fed up with it and was going to exchange it because the AI cheats...but then a 2player match with my brother changed my mind
Problem is everyone has moved onto x-boxs and gamecubes but have yet to get decent multiplayer games for these machines.
*cough*SuperMonkeyBall*cough* dunno about the xbox tho....Halo?
