Although I've had Dance Dance Revolution Konamix for ages, I wasn't able to play it for most of that time due to living on a second floor apartment with thin walls/floors/ceilings. (The game even helpfully provides a warning that states "Be careful... not to disturb others with step vibrations.") Anyway, after moving to a place where there's no neighbor to annoy underneath me I've been able to finally try out DDR myself.
Basically the game was what I expected it would be, which is a straightforward dance game. "Straightforward" definitely doesn't mean easy, though. Each track is given a rating out of 9 feet (not sure why they didn't just rate them out of 10) and divided into three categories, "Basic", "Trick", and "Maniac". I started off with the Basic and although it took a little while to find my "footing", I got to a point where I was able to do pretty well. The Trick level is significantly more difficult, as it has many more 16th-note steps, i.e. twice the speed as regular steps, as well as many more complicated two-foot steps, often requiring you to jump from one two-foot step to another two-foot step. I barely touched the Maniac level, as Trick was tricky enough for me.
Anyway, there's not a whole lot more I need to get into. If you know anything about the DDR series you know what to expect. The music was pretty decent, and had a good mix of techno, R&B, etc., and the on-screen dance characters were fairly entertaining. No story mode or anything, but it's definitely not needed. My only complaint is that the ranking system is a bit too rigid, as you're only awarded an A if you get a full combo, i.e. "perfect" or "great" on every step with none missed.
Although the game is fun and requires much more activity than other fitness-oriented games I've played, I'm not enough of a high score chaser or perfectionist to play it for extended periods of time. Still, there's no denying the series' cultural impact and influence, so much so that it's earned a place on my "Greatest Games of All Time" list. I'm sure I'll be visiting its other entries, but for now I'm going to shelve this one in favor of a newer (to me, anyway), shinier fitness-oriented game. Stay tuned...
