Ok I've got a question. Last Christmas I recieved the PC version of Star Wars Knights Of The Old Republic and I own a G5 dual core tower. So obviously I can't play the game, I have no reciept and the game is still sealed. If I take it back somewhere that's still a difference on $19.99 of the PC version and the $50 Mac version. Anyone have any suggestions or am I basically screwed? I could try taking the game back with no reciept and it's still sealed, but I don't want to pay the difference in cash.
