Does anyone have lotion?
*Raises hand*
Is mayonnaise a lotion?
Nintendo has Super Smash Bros, a game that pits numerous characters from a wide range of games against each other, Sony has PlayStation All-Stars Battle Royale, a similar game to Super Smash Bros, but where is Microsoft's version? Even Sony managed to find enough characters to create a decent game, so why not an Xbox 360 version?
Some obvious ones that I'm sure we will all think of are Master Chief and Marcus Fenix, as well as other characters from their respective games, but who else could be in the game?
And for fun, if you could include two "guest" characters either from multi-platform games or exclusives from Sony or Nintendo, who would you include?
