Yu-Gi-Oh! Capsule Monster Coliseum

'Yu-Gi-Oh! Capsule Monster Coliseum' 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. His fellow competitors include his friends, rivals from Duelist Kingdom and Battle City, and the other Millennium Item wielders, such as Maximillion Pegasus, Shadi, and Marik Ishtar.

Gameplay
The game has some deviations from its manga counterpart. Both players have a piece called a "Symbol" (Which Mattel later called 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 in the game, but you do not get the material monsters back afterward; only the fusion. Some terrain on the field can make a monster stronger or weaker depending on the monster's attribute. The total amount of monsters there are is 200.
