To parents who are considering purchasing this game for your children: If you prefer your children to refrain from hearing occasional profane language or references to sex, this would NOT be a good choice! I let my kids play it at a friend's house, and after trying a few songs, they found some that were more appropriate, like Joan Jett's "I Love Rock 'N Roll." Regarding learning rhythm in music, it's a phenomenal tool for teaching children or adults, but I just wish they provided a larger selection of songs that aren't as "nasty." It is definitely a fun game, but the content definitely has me concerned. Wish they'd come out with a version for families like us who are offended by some of the songs on this first version of Guitar Hero. It is what it is, and that's what most of it is: offensive.
