THE GOOD:Song choice. Some songs are just so good not to play!
Also the training/lesson modes are helpful. Even the "Information" screen is cool. It tells you more stuff about your favorite songs.
THE BAD:
If your mat sucks... well, yea, that sucks. Some songs aren't good. *cough* 5.1.1 *cough*
SUMMARY:
This is better of the 2 DDR games released at stateside (Konamix and MAX).
This has better songs, more songs, (over 60!), and better graphics. I'm glad that Konami has added songs from MAX2 and MAX from the arcade. So you can practice at home, and show your skills in the arcade. But once you get passed the "Standerd" level, some mats are bad at handling "heavy" levels. So that's when you basicly have to start playing at the arcade to practice "Heavy songs"
Really, the only bad thing about this game is the mat problems. That and the frustration on doing Oni courses!
