the character roaming around miniature terrain, as found in the earlier Final Fantasy games, every area is represented proportionally. The player navigates the overworld on foot, Chocobo, or by airship. Players may save their game to a memory card using save crystals or gate crystals, and may use the latter to teleport between gate crystals. An in-game bestiary provides incidental information about the world of Final Fantasy XII. Final Fantasy XII restructures the system of earning gil, the currency of the Final Fantasy games; instead of gil, most enemies drop "loot" which can be sold at shops. This ties into a new battle mechanic which rewards the player with improved loot for slaying a particular type of enemy multiple times in a row. Selling different types of loot also unlocks a bazaar option in shops, which provides items at a lower cost, or items exclusive to the bazaar.

When a character or enemy begins an action, target lines connect characters to other party members or enemies; different colors represent the different types of action. The player may swap to and issue commands to any of the three characters in the party, but guest characters are controlled by artificial intelligence (AI). Battle commands are initiated through a series of menus, and include Attack, Magicks, Technicks, Mist, Gambits, and Items. The player may switch any active character with an inactive character at any time, unless the active character is targeted by an attack or ability. Characters who are knocked out may also be substituted.

Using gambits, the player may set reactions to different stimuli for each character. Each gambit consists of three parts: a target, an action, and a priority. The target specifies which ally or foe to act
