Yu-Gi-Oh! Capsule Monster Coliseum

Yu-Gi-Oh! Capsule Monster Colosseum was released for the Playstation 2 in 2004. Unlike other Yu-Gi-Oh video games it focused on the lesser known Capsule Monsters game featured in the Manga. (This was before the release of the Capsule Monsters anime spin off)

Story
In campaign mode, the player assumes the role of Yami Yugi as he competes in a capsule monsters tournament. All his competators derive from the Battle City arc, including Marik and his dark alter ego.

Gameplay
The game has some deviations from its manga counterpart. Both players have a piece called a "Symbol" (Which Mattel would later call a King Monster) and a number of monsters depending on piece limit and amount of monster points to spend. The object of the game is to use your monsters to either destroy all your opponent's monsters, or their symbol. After games, monsters can level up making them stronger in the next game. Monsters can fuse ingame, but you do not get the material monsters back afterwards, only the fusion. Some terrian on the field can make a monster stronger or weaker depending on the monster's attribute.
