Summation: If you have an Xbox and haven't played GTA 3 or GTA: VC, go freaking buy this RIGHT FREAKING NOW. If you haven't played GTA 3 or GTA:VC and don't have an Xbox, go buy this and an Xbox RIGHT FREAKING NOW. If you have a PS2 and an Xbox, and own both of the games on PS2, and want to see how they are when they're done right, go buy this RIGHT FREAKING NOW. If you're Dave Ham, this is a great excuse to spend $50, so go buy this RIGHT FREAKING NOW.
Oh yeah, and the load times are basically gone. Thank Christ.
(It sure does look purdy. I will buy this and start raving about it in approximately one week.)
