According to ESRB, this game contains: Comic Mischief
Parents should run out and grab this game. It's non-violent, enjoyable for kids of all ages, features great music and is a reasonable source of exercise.
Music game fans should have this already. As I mentioned in the review, Samba de Amigo is a very expensive game. $40 for the game itself, and $80 for a pair of less-than-perfectly-accurate maracas from Sega. Playing Samba de Amigo without the maracas is like Sumo without the big fat guys in diapers -- its just not the same. If there's any possible way to get two sets of maracas, do so -- it's nearly twice as much fun to have someone playing along with you. There are various cheaper third-party maracas available, but all that I have read about break easily and are much less accurate.
Conquering gamers that enjoy completing games only to move onto the next one will find Samba's limited set of secrets quickly plundered, but everyone else should be able to come back time and again to enjoy all the songs on all the difficulties.
Overly serious individuals that don't think monkeys wearing sombreros and silly poses are funny shouldn't pick up this game under any circumstances, lest a smile appear on their face.
