Bah.....I'll wait until a couple months after the game is released anyways to purchase it. I mean with the quality of "FINISHED" pc games companies are releasing these days, I can only imagine how many issues a leaked game will have.
For instance I reacently purchased NFS:HP from EA no less, and while I have enjoyed the game from an objective standpoint, to a normal gamer it is complete rubish. The game wouldn't even run at launch on quad core pc's, then they "patched it" and it ran, but at worse than console framerates, they patched it again, without addressing the framerate issue, and now the multiplayer is so fragmented by version incompatabilities since the retail version doesn't auto-update that it is difficult to get a good race going. Usually only one class of cars in one race type has a good group going....if you're lucky. All in all a crappy gaming experience.
