I'm 100% with Kev on this, unless you've played PGR2 and seen it in motion don't slag it off, I have said and most likely will continue to say that I prefer the GT games but PGR2 is a fantastic game, the cars although they don't handle as accurate as in GT still feel realistic and the graphics ARE better than what the PS2 can handle.
I'd like to add that this is in no way whatsoever an attempt to put GT4 down cos GT4 will be IMO a better game overall that PGR2 but some people just have no comon sence and/or they will slag things off for the sake of it.
