Nintendo owners can get DDR Mario Mix for the GameCube (25 songs that include remixes of classic Nintendo themes), and if you have a Japanese Game Boy Color (or newer), you can import 5 different Game Boy games for your fingers.
Even the Sega Dreamcast has a version of DDR, but you have to import it from Japan and the Dreamcast dance pads are a pain to find if you don't have the PlayStation to Dreamcast adapter.
Some of the songs you can find on later versions of DDR, but if you want to be a true DDRist (I guess I made another term up, eh?) with a complete collection, then you need this one.
Thus, all the potential for greatness that would have set the Wii version of DDR apart and above the others is squandered on what feels more like a cheap gimmick than anything else.
DDR Freak offers song lists, step charts, tournament videos, machine locations for the full-sized arcade version of the game, an online community, and other helpful resources.
