Absolutely excellent if you liked ICO at all you will go crazy for Colossus my wife even loves it and she hates every game i have. In a nutshell you hunt down these creatures called the collosi that are easily the most impressive creatures created for any system some of these things are as big as skyscrapers. Graphics are excellent but in more of a artisitc way than a polygon pushing way. Anyway i really recommend it and if you want a game thats different than anything else you have played pick it up.
