The Team ICO series is thus far a trilogy of games featuring a shared world and intuitive action/adventure gameplay design. It's not a series in the sense of the Halo
or Resident Evil
series, and is more of a universe that three stand-alone games take place in. The games focus on adventurers in barren worlds, working as a team - with one player controlling a hero and the companion controlled by the PC, accomplishing things together that they could not do alone. There tend to be few usable objects, and the main character's inventory is highly limited. Most of the puzzles involve creative use of the nearby terrain in an intuitive way. Dialogue is sparse, and the story of each game may seem very minimal, but on later analysis opens itself up to many interpretations.
The three games are all connected by the appearance of horns on certain characters, which mark them as sharing the blood of a god.
- ICO: A boy with horns is imprisoned in an ancient castle. There he meets a girl who is also imprisoned there. The two attempt to escape from the castle.
- Shadow of the Colossus: A young man goes on a journey with his trusty horse to revive a girl. He must slay a series of giants called Colossi to do so.
- The Last Guardian: A boy goes on a journey with a (colossus-like) baby horned gryphon and together they mature and become friends. Currently in Development Hell.
This series provides examples of:
- A Boy and His X
- Death by Newbery Medal - From simply looking at the trailer for The Last Guardian, some just get the impression that's it's hardly likely that both the kid and the baby griffin are going to survive the game.
- Death of the Author: Invoked by series director Fumito Ueda. He's said that his interpretations are only his own, and encourages fans to come up with their own stories. The fandom has certainly run with that command - any given two fans will probably have at least mildly different interpretations on what exactly is going on in each game and how they're connected.
- Horned Humanoid: Shows up in ICO and Shadow of the Colossus, with the protagonist of the latter being the first chronological example.
- Human Sacrifice: A weirdly common motif.
- Kid Hero: Ico and The Last Guardian both have one. Wander can't be very old either.
- With the latter, that would all depend on one's definition of the word 'Hero'
- Living Shadow: Both in Ico and Shadow of the Colossus. In Ico, they're your enemies, born from the souls of the sacrificed boys in the castle. In Shadow of the Colossus, they're spirits of each slain Colossus, but all they do is stare before you wake up.
- Minimalism: The games are stripped down to their core gameplay elements, with few distractions and almost no sidequests. Shadow of the Colossus is notable because the player has the same two weapons for the whole game.
- Pet Interface: Agro in Shadow of Colossus and the gryphon in The Last Guardian.
- Scenery Porn: Orgies of it.
- Thematic Series: Team ICO is one of the few developers that invoke this trope deliberately, instead of as a way to get around loss of copyright. ICO and Shadow of the Colossus (and presumably The Last Guardian) all share a common aesthetic and themes, as well as being placed in the action adventure genre, but are otherwise stand-alone titles. There are loose storyline connections, but they are almost completely inconsequential to the game experience.
