I just purchased this game for my son to use on his 3 year old iMAC G4 and thought it would work. I got home and was reading the requirements and see that it might not. Does anyone know if it will or not? His computer is an iMac PowerPC G4 - as purchased - 1GHz, with 512MB RAM and 32MB nvidia (I think this is the problem??????) The game's box says it requires a 64MB Video card, but I didn't know if it might work anyway??? Sorry - I don't know much about video card requirements and gaming- I prob. sound like an idiot.
