What do you think? In my opinion that's a tough call 'cause Enix has done a lot of great games, but if I had to pick one I'd lean toward Bust a Groove since it's way too easy, more repetative than a broken record, and provides minimal replay value if you're looking at things in an overly optimistic sense. There's no gameplay variety at all. Once you've learned the moves and the timing (which really doesn't take long at all) every stage is exactly the same as the last. The worst part is this came out after Konami's Bemani series, which showed that you need to give players more than an aesthetic difference to keep things interesting. On the other hand, the music was pretty fun...
