According to ESRB, this game contains: Blood and Gore, Violence
Parents probably should avoid this title for young children. The game has some particularly violent sequences at the beginning, as well as some disturbing scenes involving the Gnosis later on. It should definitely be fine for teens, but parents will need to use good judgement for pre-teens.
Fans of Xenogears will find everything they loved in Xenogears here in Xenosaga. The story revisits similar themes, and it is just as challenging and complex. Minigames are also excellent. One disappointment may be the loss of the hand drawn anime sequences. Xenosaga is completely 3D and superficially looks more like a Square RPG than it does the PlayStation classic.
Gamers in general should be aware that Xenosaga has long and frequent sequences where all a player can do is sit and watch.
Deaf and Hard of Hearing gamers will be able to follow the story easily as the game uses subtitles. However, there is a puzzle later on in the game that requires hearing in order to solve.
