i'd just like to suggest some things:
-better quality control in stepfiles. some stepfiles have no correlation with song accompanying them. for example, rondo allo turca (sp? the philip glass performance) has almost no correlation to the music. my first few times i did terribly because, in my ddr habits, i listened to the music for the beat and rhythm. i only managed to get in the top ten by ignoring the song and just watching the steps. c'mon guys, make the music relevant. (moonlight sonata is another example... just a suggestion for newer songs.)
-ffr isn't ddr. be creative. as in, instead of just "jumps" (double arrows) why not triples or quadruples? after all, this is with fingers and not feet. (then again, maybe revoulationary etude uses triples and its the reason why i can't read that song worth crap).
-what about "chaining" songs? like say, have one song that if you do well on, immediately takes you to another song which you have to do even better on to continue, and you can henceforth improve your score cumutively on the first song's high score list? i mention this because you could do great sonatas and concertos for you classical music section
. plus, it'll allow for some extreme high score challenges when hellbeat links you to caprice links you to revolutionary etude. but of course only if you do really well on hellbeat (perhaps 50th percentile) and even better on caprice (perhaps 75 percentile?)
