According to ESRB, this game contains: Mild Cartoon Violence
Parents have nothing to worry about. There's no graphic violence, no sexual content, and no bad language whatsoever. There's some stereotyping of Italian immigrants (mostly in the voices of Mario and his brother Luigi), but that's the only objectionable content there is.
Mario fans will find plenty to love. Basic staples of the series are still here—the puzzles, the pipes, the quirky items, the acrobatic jumping—and enough has been added to make even those familiar things feel fresh and new. In particular, playing around in outer space with wonky gravity is a lot of fun.
Gamers who don't like Mario at all won't find anything in Super Mario Galaxy to convert them. Everything you dislike about the Super Mario series is probably still here, too.
Deaf and Hard of Hearing gamers should have no problems. All speech and relevant information is in text, and there are no auditory cues that don't have visual cues paired with them.
