I already own GTA:VC on the PS2, so I won't buy it for the PC.
My game wish list is: Gran Turismo 4 and Driver 3.
And, if the rumors are true, GTA: San Andreas. It may be the same game as GTA3 and VC, but jumping over those hills (with a great view as with VC) while getting rid from cops, wow...
I like games with cars in it, not particularly race games (exception: Gran Turismo, just for the looks).
