Parents shouldn't find DDR offensive at all, but should be prepared to shell out the necessary cash for the essential dance mat controller.
DDR newbies will find Extreme to be a good jumping-off point into the series, since it has a thorough Lesson Mode that introduces players to basic steps and techniques.
Health-conscious gamers can use the Workout Mode to feel good about themselves. Playing a session of DDR is hardly the equivalent of jogging or cross-country skiing, but it's not a bad way for the otherwise sedentary gamer to get some exercise.
Players without dance mats can buy the version of Extreme that comes bundled with an official Konami soft pad, although once they hit the intermediate to advanced stage they'll want to think about upgrading to a Red Octane semi-hard or metal pad (www.redoctane.com).
Deaf and Hard of Hearing gamers will obviously miss out on the soundtrack, which is an important component of any rhythm-action game. It is however more or less possible to follow along based on rhythm alone.
