The one time I played DDR, I was playing stip DDR, and even then it was only fun because I was teasing the other guys about being out of shape. ^.^;
(by the way, it's "strip")
Strip DDR? LOL! Man, I'll challenge you to that anytime... Just kidding.
As for the actual tournament...
Hi! I'm the guy you were talking to by email. But I'm sure you knew that.
I said it to you before, but I'll say it publicly: if you have a lower-difficulty division with prizes, you
will get people entering it who shouldn't be. It just happens, even among relatively honest people. :?
The best I could recommend would be to make the prizes for the upper division MUCH bigger than the lower division. The difference should be big enough that no skilled player will consider entering the lower division.
But I'd really just recommend not splitting it at all, because it's not really fair to the players who get 4th, 5th, and 6th place (and so on down the line) in the upper division.
I think that having a Freestyle division instead would be great. However... I ran the DDR tournament last year, and I tried to have a Freestyle division, but nobody entered. If you think you can get enough people this year, then hey, go for it.
