Edit: I should have called out Universal's Men In Black Alien Attack as another example of a good game ride. It's basically just a much lager version of original Disney's Buzz Lightyear concept, except at one point you can shoot the other ride vehicles to cause them to spin (fun!). Tokyo Disney's Monsters Inc. Ride and Go Seek is an interesting concept too. It's not really a "game" ride since there's no score or win/loss element, but it is highly interactive in a very similar way.
