O.K. Buster World

O.K. Buster World is a compilation game consisting of modes from previous O.K. Buster games. It is Sony's last successful O.K. Buster title in the series before Burst Arts obtained the rights.

Gameplay
O.K. Buster World has a multitude of game modes available to the user. It contains O.K. Buster and O.K. Buster II, as well as a RPG-styled Venture mode in which the player plays as Erla and battles against the rest of the cast in dungeons. It also houses a Battle Craze mode in which you have to face either 10, 20, or 30 opponents, as well as two multiplayer modes which can be played with either other players or AI additions.

For the Venture mode itself, it allowed the player to customize the armory in ways in which made Erla stronger with a double-edged sword effect. For example, one could remove the Oracle Rings in order to beef up her attack at the expense of being unable to control the O.K. itself, and the amount of experience gained and gold won was relative to how big a chain was scored and how quickly the opponents were defeated.

The key point in the gameplay of World is that the player can choose a ruleset from either O.K. Buster, O.K. Buster II, O.K. Buster Mega, and O.K. Buster 4ce. This can effectively lead to multiplayer battles where each player plays with independent or customized rules. This game also allowed for team battles to take place. A special multiplayer mode was made available in this game, known as Hunting Mode, which was adapted in O.K. Buster 10th Anniversary as its Travel Mode.
