People complain about a lot of these with this game, but I really enjoyed it.

Fun game: Yes, indeed. VERY addictive with all of its quirks.
Job System: Good system. Ability to change jobs mid battle and to choose what abilities to learn? What's not to love?
Battle System: My favorite ATB system, and system overall. Fast paced, especially when cranked at max speed.
Story: Not a great story, but that may be because the game is non linear also. If I was worried about story number one, I would've bought a book instead. However, I'd rather play this fun game.
Difficulty: Varies, depending on how much or little you do.

Someone mentioned it was about $12 used? Hell, I've found it at Best Buy for $12 new!
