Parents might want to reserve this title for older kids. There are a few scenes that might be too much for younger kids to handle, and of course the main gameplay mechanic is gunplay, although there are no bullets. Still, there's not a whole lot of difference between an exploding grenade and an exploding bat head, so the end result is basically the same. Occasionally there was some mature language peppered in amongst the dialogue, although nothing approaching the extreme end of the scale. There are no sexual situations.
Action gamers should absolutely pick up this game. It's beautiful, it feels just right, and the way the transition is handled for switching between first-and third-person viewpoints should become the standard for the rest of the industry. The shooting is strategic, yet always exciting and fast-paced. In this humble reviewer's opinion, the almighty Halo could learn more than a couple things from this game.
Deaf and Hard of Hearing gamers are screwed. The game can certainly be played visually, but there are lots of audio cues which play a big role in gameplay, not to mention the fact that there are absolutely no subtitles to be seen anywhere on the disc. It's extremely disappointing given the otherwise high quality of the game overall.The graphics are great and the control is tight, but you'll have to find an FAQ to figure out what the heck is going on in the story. (It's also worth noting for hearing gamers that the voicework is good but many of the characters have weird accents, or sometimes there are noises in the background that make it hard to hear what's being said.)
