I'm onyl a short ways into FFXII (for those who have played, the last thing i remember is the lost princess is hiding out for now and i need to go south during the rainy season after that crystal blew up some airship fleet)
FFT has as much to do with FFTA as apples has to do with adam's apples. They may sound like the same game, but the first game is a decently written (for the most part), in-depth, story-driven, extremely difficult strategy game. The second is poorly written (for the most part), lacks depth, pisses on story, and is only difficult because of annoying rules put in there to distract you from how thin the rest of the game is.
Granted, FFTA is a pretty game; that's the only reason i downloaded it. Of course, it's not pretty enough to buy. I own the seiken densetsu series up through GBA, which i suppoes is proof that i do enjoy videogames, particularly ones that manage to be attractive and have good gameplay.
