i have played it on the PS2, but never the PC port, but i am assuming they are identical. It was a fun game, in rockstar games fashion, very controversial. blood/guts/language, etc was all very dark and disturbing, but thats any rockstar title. Overall i enjoyed the game, and the shock value was huge, but once the shock value wears off, it offers very little in the way of innovation and replayablitly..i would venture to say that it really just gets repetative. Also, there was one level in particular that was so hard, it almost made me quit playing and rerurn the CD, so be prepared for some monumental frustration if you plan on seeing the predictable ending.
Overall, i would say it is a very fun game, but replayability value is nonexistent. rent it for your PS2 Xbox
