hmmmmmm...
Are you sure you want to squeeze as many noise-button-toys into one box as possible, and make them simultaneously accessible by your kids?

Maybe you should hide an "oops it's broken" switch in there so that every now and then you'll have to spend a week or two "fixing it" when it "breaks"....

That said, there were younger kids over this holiday, and they do seem to enjoy waggling the joysticks and buttons around far more than actually trying to play a game.
