According to ESRB, this game contains: Mild Violence
Parents don't have anything to fear. The difficulty may be a wee bit higher than you'd want for young kids, but there aren't any scenes containing sex, graphic violence or questionable language. With the name "Disney" on the front, you pretty much know what you're in for.
Platformer fans might be interested, but only if you've played through the genre's "big names" like Jak & Daxter, Ratchet & Clank and Sly Cooper. Treasure Planet isn't the worst game out there, but the platforming action is uninspired and becomes monotonous far too soon.
Futuristic racing fans should definitely check out the game's outstanding Solar Surfing, but only if you think you'll be able to tolerate the tedious platforming in between the good stuff.
Deaf and Hard of Hearing gamers get the old "half and half". The game does feature subtitles for the in-game dialogue, but leaves the text out for all of the animated scenes from the film.
