I find it strange that no one has commented on this yet. Maybe everyone is playing Enthusia.
This is a really good game with solid physics and reasonably good A.I. Getting everything can be expensive, or most of it, but sales like these are perfect for giving you a good bunch of toys to play with. I've been playing my synthesizers lately, but am intending to get back into some RaceRoom action, and probably GT6 and AC, this Memorial Day weekend.
