My #46 is GRID on the 360. Well, you could also count it for the PS3, but I haven't played that version, so I left it out. I own the DS version, but that one is a whole lot different. It's good for what's possible on the DS, but no match for the home console versions.
An accurate description of GRID is: If this game was a Porsche, Forza and Gran Turismo would be Trabis.
