After a lot more research, I believe it is a turn-based fantasy-themed multi-character RPG in traditional Japanese cutesy graphics. Is this right?
Kind of, but not really. FFT came out for the original PSX several years ago. It’s really not like any of the other final fantasy games. Like I’ve tried to say before, it’s more like an rpg, super-chess. Play consists of battles surrounded by plot line. Battle takes place on an isometric board laid out like a chess board, along with varying heights for each tile, and varying terrain for each tile (for example grass, water, lava, stone, etc…). Play ensues one piece/character at a time. Each character gets a move turn and an attack turn. Each character has their own special sets of stats and capabilities which are related to their class. Much like chess, each different type of attack has a special range and an area of affect. For example, a squire has the capability to throw a stone a total distance of three tiles (or something like that). The stone only hits a single tile. Unlike chess, height is also factored into the equation, and movement capabilities are separated from attack capabilities. As another example, a wizard may be able to only move three tiles, but he can cast spells which reach six tiles away and have an area of effect of eight tiles. Every action you take in battle garners your characters more experience. As they gain more experience, they can learn cool new skills from their class, and gain more levels. As they gain more levels you can change them into more powerful classes - like ninjas, summoners, and calculators. Of course, in Squaresoft fashion, the special characters in the game that are important to the plotline have their own cool unique classes and skills. On top of all that, characters can all be equipped with special items that affect their movement, attack damage, available capabilities, etc…
Anyway, the game is very good. The official home page appears to be at http://www.squaresoft.com/web/games/fft/fft-index3.html but I think you have got to play it to really understand it.
It sounds like FFTA is a fairly straightforward port of FFT to the GBA, just like many of the other games that exist for the GBA.
