It's a nice tenth-anniversary installment to the popular dance franchise. It has a nice song selection, and the levels vary for each song, so there's a song for players of all skill to play. You can customize arrows, choose dancers, etc. Many nice features.
The only bad thing would have to be the dancers- some of them dance in a suggestive manner. Oh, and some lyrics might me questionable, but nothing too bad.
All in all, great DDR game, and great video game :P
