ICO is such an amazing game, it's hard to find the words to do it justice. The castle it's set in creates such an eerie, isolated atomsphere while the animation and tiny amount of spoken dialogue make you care deeply about the two main characters despite the complete lack of written dialogue. The whole thing is so subtle and masterful, it's like the gaming version of classical music. Or something. If you've played it you'll know what I'm trying to say here and if you haven't played it, you should make it your mission to.
