Final Fantasy Tactics: Rebirth (FFT: Rebirth) is a modification for Final Fantasy Tactics which features a rebalancing of almost everything in the game, in particular classes but also items, abilities, characters, random encounters, and storyline battles. The modification also features a few new graphics and a complete overhaul of the speed system. This mod caters to an audience already familiar with Final Fantasy Tactics - those who wish that some of the weaker classes were better balanced and want some new interesting and refreshing encounters.
A short video displaying some of the new random encounters. This particular one shows a fight between two dragon hordes on Mandalia Plains. In Rebirth each area now has a hard random encounter which happens 40% of the time when approaching a particular area from a given direction. For example when approaching the Mandalia Plains from the south you have a 40% chance of this battle. Approaching from other directions will spawn the normal unchanged encounters.
