According to ESRB, this game contains: Animated Blood, Animated Violence
Parents should note that Soul Reaver revolves around the undead and is extremely dark and bloodily violent; probably better suited for more mature gamers. But if pure action with a touch of depth and substance is more your thing, Legacy Of Kain: Soul Reaver is sure to please.
If you enjoy labyrinth spelunking along the lines of The Legend Of Zelda: Ocarina Of Time and Tomb Raider, then Legacy Of Kain: Soul Reaver should be right up your alley. Just be weary that this game is action/adventure-intensive and once it gets going, it doesn't stop -- Energizer Bunny style. So if you like soup and salad with your meat and potatoes, you'll probably want to look for a more well-rounded game.
