Final Fantasy XII: Revenant Wings is a real-time strategy RPG developed by Square Enix and Think & Feel Inc. for the Nintendo DS. It is a spinoff to the best-selling 2006 PlayStation 2 role-playing game Final Fantasy XII. One year after the events of Final Fantasy XII, the protagonist Vaan is now a sky pirate possessing his own airship. He is joined in a new quest by his friend and navigator Penelo, other returning characters from the original title, as well as new characters such as Llyud, a member of the Aegyl race who have wings protruding from their backs. The North American release of the game was rebalanced to be more difficult than the Japanese version, and was released on November 20, 2007.

The game combines elements of both RTS (Real Time Strategy) titles with RPG ones to offer the player a complete experience in the Final Fantasy universe. As always, an full motion cut opening scene introduces the player into the story of the game. The game also has elements from the Final Fantasy Tactics series and can be controlled using only the stylus of the Nintendo DS. The party being controlled by the player can attack automatically when it encounters enemies and the player can issue new orders or change the target by using the stylus.
