And VII!
They managed to look beyond the cries of "KEEP IT TURN BASED" and identify what people actually loved about VII's battle systems, and kept that in place. And, dare I say it, even expanded and improved upon it? By reducing the 'attack' button to a small damage thing that just helps charge your proper abilities, there's gonna be so much less attack-spamming your way through the game and way more incentive to use your cool stuff.
