According to ESRB, this game contains: Language, Mild Suggestive Themes, Use of Alcohol, Violence
Parents should be fine with their teenage children playing this game. Yes, it's a little on the violent side, but only insofar as it needs to be to depict the war realistically. The game's lack of other prurient content does hurt the realism factor a little, as there's none of the swearing, alcohol or wanton sexuality that people expect from sailors.
Multiplayer gamers should consider picking this title up, as the naval combat is every bit as entertaining against real people as it is against the computer.
Deaf and Hard of Hearing gamers will be fine with the game, as it features subtitles for dialogue and key information printed on screen. There aren't any important audio cues to speak of, and a handy radar lets the player know when enemy planes and ships are sneaking up on them.
