Great game!
The songs are long, but it makes for a good work out. And for people who only have a Gamecube, this is a good game to get, since DDR isn’t on the GC.
The default dance mode is really weird, the arrows come out from the middle and go out, it's really confusing. But you can change the settings to DDR-style, which makes the game much more enjoyable.
No matter what other people say, I think this game is great!
