Depends on your preference, I guess...

Do you regularly use your PC for gaming? Obviously don't go for the PC version if your PC isn't very good... you may run into problems that you otherwise would not if you got the PS3 version... or if you don't even enjoy playing video games on the PC.

I have the PC version simply because I prefer playing games on the PC no matter what. I have a modern rig, so I can run things just fine. Plus the graphics are just excellent.

I'm considering getting the PS3 version, though. That way I can play while laying in bed
