If you've never played this game then seeing some screenshots or reading about how beautiful it was will probably not mean much to you. But I don't know of anyone who has played Ico who didn't step away without some sort of emotional experience, without some real connection to this game.
The article says this is a game you should play alone. I understand, but I don't really agree. I played through this game with a good friend, and whether you're playing or simply watching, it's a great experience either way.
