I, too, love DDR! I first played it at an arcade like a year ago and ohhh, it was so so addictive, so then I had to buy it.
Actually, I didn't end up buying it. I took a friend's advice and downloaded
StepMania, which is just like DDR only cooler because you can search places like
bemanistyle.com for simfiles of songs that you like. People I guess somehow program their own. So playing DDR to Christian songs is possible. (There's some songs I'd love to play DDR to, but I don't have enough confidence in my sense of rhythm to even look into how these people program their own simfiles. I just download them and leave happy comments.)
So, yeah, I basically play DDR on my computer. Which level really depends on the song. Like, from the fourth mix alone I can pass "1,2,3,4,007" on Heavy, but I despair of ever passing "Paranoia Evolution" on any level.
I love my mat. I thought I needed a metal one, but
this one is working beautifully.
