I guess I'd post How to win a motorcar race to start off discussions on realest game ever. If you disagree, that's fine, but this guy won a real race just by training on the PS3 game! However don't try any tricks on public roads in your fake-WOFed honda civic okay ...
also this thread will probably be locked till March 2010 ... :(
(having said that he probably has a $100,000 simulator attached to his PS3 and not just a joystick like i have)
