Parents should steer kids away from the game. The nature of the environmental puzzles might be too challenging for little ones, and the combat scenes can be a little intense and frustrating at times. There is no questionable language, but there is one very mild scene of intimacy taking place in a secluded bath/pool area.
Adventure gamers are in for a treat, and Tomb Raider fans—Lara is so over. Give the Prince a whirl and you'll immediately see everything that's wrong with Tomb Raider because Prince of Persia gets it all right, at least from a technical perspective. For above average design, programming excellence, and a ton of cool style, it's a winner on all counts.
ICO fans will definitely be interested in this game. In my opinion, it's not an overall better experience than ICO is, but with both more combat and a more machismo, it could easily be called a semi-sequel.
Deaf and Hard of Hearing gamers are out of luck here. There aren't any subtitles for the CG cutscenes, nor any for the Prince's internal commentary. You can select from three spoken languages, but no captions—come on, Ubisoft.
