A gamer one would be rather funny.
Haha for instance for the Wii and against the PS3 or Xbox 360, you could have two sides fighting against each other in one bit, and one gropus holding the wii controller, and the other groups holding a standard controller
Th wii gang only have to point and shoot to hurt the other group, but the others have to move the analog, and you could have targets and the ones with analog could have them moving really slow and unnaccurate, hitting the group in a very awquad way.
Then the Wii people would be like simply pointing, and the target would appear straight away on the other groups heads, and they'd be like "gulp".
Just an example
And we know what the Beatles are, but what are you trying to get across?
