Well I had alot of DDR games for the ps2, and they were 3rd party pads that had plug tips for the gamecube and I tried to hook them up to my wii and they plugged right in!
Any DDR game is fun, especially when its more than one person, so more than likely with the wii's motion controls and how the game box boasts about being able to use the wiimote as well to send obstacles flying into your opponents dancing place sounds fun and real interactive! And on this DDR, up to for people can play at once...it just makes me wonder if it will be like patting your head and rubbing your stomach. Oh well, I saw a used copy at a Gamestop for 39.99 so if its still there next week, Im sold.
no idea if the pad is wireless or not though.
