I'm not a video person, and tend to avoid arcades, but with that being said, my 11 year old and I just returned from SF and one of the funnest (sp) things we did was "virtual bowling" at the Metreon. Try it. It's really pretty fun, and you get a choice of backdrops. We first tried Tokyo, then the Ship, and finally Cable Cars in SF.
It definitely qualifies as different!
