Re: GT4 pc?
Not even a single chance. When's the last time you remember a "Gran Turismo" or a "Tekken" or a "Ridge Racer" coming out as a PC version? That's right, never.. The only time you'd been able to play the older ones was on PS1 emulators, and seeing how PS2 emulators are progressing, there is a 99.9% chance that you will never see GT4 run through an emulator and 100% chance there will be no PC version.
You'll have to buy a PS2 in order to play the game. I don't have one, but I'll borrow one from a friend for about a month to play this game.
