Ico has a lot of issues. The combat is dull and repetitive, all the enemies are basically the same. Some puzzles are too obtuse. Dragging the girl everywhere can get tedious and frustrating. And yet, it's one of the most engrossing experiences I have ever played. The game accomplishes to make you care for the girl, something almost every other game with scort missions can't manage to do. The atmosphere is unique. The story is vague but with enough clues to let the players figure things out for themselves and the gameplay transmits being overwhelmed by the circumstances and out of your comfort zone.
