According to the ESRB, this game contains: Mild Language, Violence
Parents have little to sweat. It's an action-adventure with only mild violence, much in the vein of the Indiana Jones films.
Xbox owners, and especially Xbox Live subscribers, should give the game a look, though a rental is more prudent than a purchase on this one—that is of course you are a die-hard fan of flying games. If you enjoy games like the Rogue Squadron series, you'll definitely get a kick out of Crimson Skies.
Deaf and Hard of Hearing gamers will miss out on the banter and the some significant audio cues, but the game will still be playable.
