Based on the kinds of games you usually prefer, I'd actually be hesitant to recommend ICO to you. As much as I love the game, I recognize that it's not for everyone. It's a very atypical experience that can't be appreciated if you attempt to draw a 1:1 comparison between its elements and those of other 3D action/adventure games. I would certainly hope that you give it a try, but I just want to give you fair warning that it may not be your cup of tea.
Its sequel, Shadow of the Colossus, more closely aligns with typical action/adventure, so I can heartily recommend that one despite some similar eccentricities compared to the rest of the genre.
