Released: 2001
Developer/Publisher: Team Ico for Sony Computer Entertainment
Platform(s): PS2

This commercial flop became a cult classic thanks to a sweeping, minimalist design that pushes the artistic envelope. In an often silent, romantic adventure, a boy with horns named Ico gets locked in a castle, where he meets another prisoner named Yorba, who happens to be the daughter of the castle's queen. The two spend the game trying to escape, holding hands the entire time. Adorable.

In 2005, the team behind Ico released a loose prequel called Shadow of the Colossus, which appears later on this list.
