Yep, I am talking about Dissidia: Final Fantasy which would be released for the Playstation Portable this 2009.
The game can be classified as a RPG, since it uses progressive controls, and a fighting game, as well mainly because of the way the battles were illustrated and iterated for the game. The story goes like this: two entities of good and evil(Cosmos and Chaos) waged war on each other, causing the order of the multiverse to collapse. When Chaos' army of villains began overwhelming the peace of the universes, Cosmos recruits a couple of heroes from the diff. Final Fantasy universes in order to counter the villains and defeat Chaos to restore the order of the multiverse.
Here are the diff. characters that will be present for the game:
