I've never played Ico, which I heard was an awesome game, but I do know that the main character is a child warrior with horns on his head who happens to be trapped in a castle. So, how does Shadow of the Colossus relate to Ico, if at all? Does the horned child in SOTC grow up to be the warrior child of Ico, essentially making SOTC a prequel story for ICO? Anyway, I was just curious about the connection between the two games. If anyone had any answers to my question, I would very much appreciate it. And by the way, SOTC was one of the best games I've ever played. It was well worth my time.

AS I see it, at the end of SotC, Mono and presumably Wander are seen in the Secret Garden. It's been confirmed that this is what started the line of horned children. In Ico, the main character of the same name is horned, but he's also down the line, there have already been many before him to be sealed in a coffin in a certain room of the castle. So yes, SotC and Ico are set in the same world, but SotC is a prequel of sorts to Ico.
