I hate to say it, but underlined is untrue. I bet some nerd somewhere in some mom's basement has already done it.
Dude, I have a PS3 and this game, no affence but this so wont work on a PC, cause you know the head movements you make? you move the controller to move your head, so it wouldn't work on a PC, same with the emotions, you would have to like remake the game to put it on the PC, but buying a PS3 is so worth it, plus you can get MGS4 :D
