If they release it for PC, I'm certainly getting it. But as of now, I'm not. This is because:
1.) I don't have a PS2.
2.) Even if I did have one, I wouldn't get it. The original GTA3 on the PS2 ran like a drunken one-legged man with a fat lady tied to his ankle. The technical aspect sucked so hard that I felt like crying every time the game stuttered. I thought the PS2 was capable of so much more. Also, the controls were a real bitch. Mouse and Keyboard for me.
