I have never played neither game, but I did see gameplay of both and tempting to try one of them. ICO looks like some Resident Evil minus the B.O.W.s and weapon. It has the changing camera angles and saving a girl who doesn't look like she'll fight back (which I had enough of that crap in RE 4). The Shadow of Colussus looks way better because it looks like some Legend of Zelda type stuff in which I love Legend of Zelda. The boss fights look fun as hell too, but which do you think is better and I should take a deeper look at?
Ico actually has a better story in my opinion, but ultimately Shadow of the Colossus tops the 2001 classic with grander valleys, gorgeous creature effects, mesmerizing sound, and sure enough the best kind of gameplay you can find.
Still though, Ico is definitely one not to be passed up. The girl in the game is the only one capable of opening doors while Ico is the only one capable of defending her with a stick. It shouldn't be too difficult to imagine that kind of setup.
I liked Ico more
Also it would be cool if Ico and Yorda were a character, like Ice Climbers, but Yorda is invincible but immobile.
And if you press circle, you can call Yorda or make her move with you, and all the other directions would be Yorda attacks or some kind of support.
It would be amazing! xD
