The title lists three games which are similar to eachother, gameplay-wise. Ico is a game where a guy with a sword frees a girl. Nico, or more commonly called Shadow of the Colossus, is a game where a boy with a sword revives his girlfriend. Trico, a game for the PS3, is a game where a boy helps a giant creature out.
That's all nice and dandy, but I have also heard of a Shadow of the Colossus 2 in the works. Anyone know what the real deal is?
