A lot of fun, there are loads of songs of various genres and many of them are great. It's quick to learn and not too challenging. The only thing that might put new players off is the fact that some of the costumes and load screens are lewd, meaning that Steam will recommend you horny nudity games every time you play it. [This is not a problem for your boy]

Otherwise, perfect game to jam out to for as long as you feel, definitely recommend if you like rhythm games. -- Oh the devs are lame tho so I'm not buying the full version hmph
