Summary: I heard Konamix was better than MAX, but bought MAX anyway. I am a very good DDR player, I can handle most 8 footers (thats pretty hard, for those who don't play or aren't that good). I play mostly MAX on PS2 and 5th- 8th mix at the arcade (8th Mix is Extreme). Compared to these, I was disappointed with Konamix. The songlist, save for Burnin' the Floor, Matsuri Japan, Afronova, Afronova Primeval, and B4U, was pathetic, IMO.
Summary: I do not recommend this game. If you are thinking of buying this game because of some good reviews you might have seen, DONT. The songs are horrible! None of the good songs from the arcade versions are in this game. And it claims to have 50 songs but it feels more like 15, good luck finding 50. Anyway, I would wait until a decent ddr comes out in the US or if your a disney fan go for the Disney mix, that seems to be the best so far.
