I have played the PC version and liked it. That was my reasoning for buying the PS2 version. I won't bother trying to play any PC games until I get a new computer.
I disagree. I played the PS2 version and absolutely hated it. The copy I rented from a local rental store wouldn't let me save and/or I couldn't figure out how to save properly. Also, the control setup for it was horrible as you had to use both analog sticks to aim. Very frustrating. I prefer a keyboard and mouse for FPS's any day over a controller.
