I've played Tactics Advance and Tactics A2. I'm very close to beating the latter, though I haven't touched it in a month or so, and with the former I don't remember where I am, though my play time's around 60 hours. I've seen gameplay footage of the original but never tried it myself.
As I haven't played the original, nor do I know anything about the story, I can't comment on the characters.
saw your post in the "what types of videogames would you like to see" thread and you mentioned FINAL FANTASY TACTICS! I love that game, one of my favorites alongside Chrono Trigger and the Tales of series.
did you play the original, the remake, or both?
I'd say FFT is my most-played game ever, usually do a play through every year hehe. who was your favorite character? mine was Delita!
