stof thats different, mario kart does not have a story line and every1 knows that there is no chance of mario and friends appearing on any other console then nintendo systems.
But it has been rumoured of gears 3 coming to ps3 (which i, as i have stated,believe it will not happen) but talking theoreticaly, i was wondering what people thought.
