Parents will find nothing offensive about DDR, except for the one anomalous lyric mentioned in the body of the review.
DDR fanatics won't find much original content in Ultramix. The 40+ songs (as compared to 60+ on the PlayStation 2's DDRMAX incarnations) are mostly remixes from previous games that would be familiar to any long-standing fan.
DDR newbies might find it intimidating to jump right into the game given its lack of a tutorial mode, but can take advantage of Light mode (decreased number of steps), and an option in training mode to slow down the speed of the songs. Stingy gamers should avoid DDR. It's next to useless if you aren't willing to shell out for a dance pad peripheral.
Xbox Live users will be happy to learn that Ultramix supports the ability to challenge other players and download new content.
Health-conscious gamers will certainly get a challenging aerobic workout with Ultramix. It's also great for strengthening legs and core muscles.
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.
