It would be some kind of mixed combat game. Gamers would be divided into teams with different classes. For a team to be successful they must have each class represented and represented well. Here is the key: the classes are decided by the console you were playing it on.
Say for example a Star Wars game:
360 / PS3 - FPS
Wii - Swordplay and Jedi powers
DS / PSP - Strategic command of the AI teammates.
Owners of different systems would have to coorperate. Arguing over consoles would come to an end! Peace would reign on the internet! (Okay not really. Wii owners would have to rub it in that they were the Jedi.)
I'm sure there are much better examples than the one I have given. I actually imagine some senario for Wii players similar to a kicker in the NFL. You kind of make fun of him because he is so different from the rest of the team, but if you have a good one, he is priceless.
