Here are a few ridiculous ideas that could be ridiculous cool (except for the second one, no saving that one)
Samurai Showdown in a mini pagoda with four sparing pads that you have to kick or hit to register button hits. Two on either side of the screen and two below. Put the microswitches for movement in the floor DDR style.
Boonga Boonga cockpit... that doubles as a vibrating uh massager...
Superman in a telephone booth.
Monster Bash in a coffin/mausoleum.
