zag, there was nothing groundbreaking about the craptacular port of Halo 1 to the PC. It ran like crap when it was released. And I won't even go into the pistol in MP games.
As for Wildone... you bought Vista and installed you, you deal with the aftermath. If you were stupid enough to install it, you get whats coming to ya gaming wise, which is craptacular support at this time.
And as much as I love to be a PC Lover, with getting a 360 I no longer have to worry about getting Games for Vista, at least until the OS is stable, and I upgrade my system.
