Trivia
It was named #121 out of 200 of the "Greatest Games of Their Time" by EGM Issue #200 (Feb. 2006).
ICO was first intended for release on PlayStation 1. Also, Yorda was due to have horns, not lead character Ico.
The original artwork, designed by Fumito Ueda, was inspired by the works of the surrealist painter Giorgio de Chirico. For comparison, the painting The Nostalgia of the Infinite bears a strong resemblance in style to the cover art.

The US version does not contain the the second playthrough bonuses present in the European and Japanese releases. These included translated subtitles (initially indecipherable), the option to have a second player control the princess, a secret weapon, and the option to play the game with a distinct cinematic effect for certain cut-scenes. There are also changes to the shadow generation points and the AI, and the Waterfall and Windmill puzzles are less complex.
