I'm fooling around with a new game at the moment, and I was just wondering if Andrammalech or any other espers are accessible before you fight Belias.
Also, FF12 has all the mechanics to make replayability a lot more fun than most RPGs. No random encounters (i.e. no spammage of 3-5 second transition graphics), ability to skip all cutscenes, and the fact that pausing the game stops the game clock are all really nice features for a replay.
