DDR is fun. I don't care, I'll admit it - it is!
It's not even... dancing. Just hitting buttons w/ your feet in sync to the annoying ass dance music. God I hate that music..
Maybe a future version will come with a pattern analyzer, or some type of thing that lets you download song patterns to certain songs online. Download a Nine Inch Nails song.. then download the pattern for it, etc.
But yeah, I do it more for a workout instead of "just to play". I get so sweaty that I can't really play it as a party game unless I wanna be uncomfortably drenched in sweat for the remainder of the evening.
It's easy to pick up, too, if you're good w/ timing and pattern games. I was gettings As - Bs on Standard mode within a week, but tried to progress to Heavy mode and end up with mainly D averages. Can't get beyond that for the life of me. So.. I dunno, it seems like there needs to be an "inbetween" stage.
I'm thinking about getting the $300 cobalt flux pad (
