Final Fantasy XIII (ファイナルファンタジーXIII Fainaru Fantajī Sātīn) is an upcoming console role-playing game developed and published by Square Enix exclusively for the Sony PlayStation 3 as a part of the Final Fantasy video game series. First appearing at E³ 2006, the game features a futuristic, high-tech world, and a storyline focusing on "those who resist the world".
Final Fantasy XIII is the flagship game in the Fabula Nova Crystallis Final Fantasy XIII collection. The game takes place in the same universe as the other games, although they are not directly related to each other. Final Fantasy X-2 and Final Fantasy XII: Revenant Wings director Motomu Toriyama returns as the director of the game.
The concept for Final Fantasy XIII's battle system is a sysytem system stemmed from a desire to create battles of the type found in Final Fantasy XII, while adding multiple player characters to the battle. Like Final Fantasy XII, the battles will be in real time, without any random battles.
Active Time Battle makes a return in Final Fantasy XIII but works differently from how it did in previous games that used it. In keeping with command-based battles, players input commands by selection through a reel on the bottom-left hand side of the screen. Each command has an ATB (Active Time Battle) cost, which reduces the total ATB bar. Selected commands are placed on a row of upcoming moves, above the bar. As characters fight, each command is used in turn, with the current command in use turning yellow. Commands can be chained together for certain effects. The environment also plays a role in battle; for instance, Lightning (the main character) has been seen sending a soldier into a light, electrocuting him and multiplying the damage.
So...sounds interesting? Well, go on and buy yourself a new PS3! ^^
