FF12. The story and gambit system are actually pretty great.
It kept the battles fresh for me by continually fine tuning the gambits, basically programming AI for the group to handle fights on their own with no or minimal intervention. And making easy switches for different scenarios. It looked great as well, one of the last games where pre-rendered FMV felt like a reward instead of in game cut scenes you can't skip fast enough.
Of course then FF13 became the black sheep with it's completely on rails linear start. That still had a great chapter 13, but not as good as FF12.
Actually FF only kept getting worse, but FF12 was great!
