1. Dance Dance Revolution: Disney Dancing Museum (N64) 1/7

I don't know if there's a longer mode that may have more of an ending than just credits, but in trying this game and the mat out, I saw the credits roll multiple times over as I played every song available in the regular single-player mode on Normal difficulty. So I'm counting that as beaten. Looking through the manual, I see there are a bunch more songs that can be unlocked, but I'll save that for another day since I was never planning on getting invested in this right now anyway.
