Like previous games in the Final Fantasy series, Final Fantasy VIII consists of three main modes of play: the world map, field map, and battle screen. The world map is a 3D display in which the player may navigate freely across a small-scale rendering of the game world. Characters travel across the world map in a variety of ways, including by foot, car, Chocobo, train, and airship. The field map consists of controllable 3D characters overlaid on one or more 2D pre-rendered backgrounds, which represent environmental locations such as towns or forests. The battle screen is a 3D model of a location such as a street or room, where turn-based fights between playable characters and CPU-controlled enemies take place. The interface is menu-driven, as in previous titles, but with the typical weapon and armor systems removed and new features present, such as the Junction system. Also featured is a collectible card-based minigame called "Triple Triad".
