I seem to recall that FF10 used each of the four front buttons and the right trigger.
But... but... I like my battles as slow and tactical as possible.
Stupid change... WHY IS EVERYTHING CHANGING?!
I like those type of battles as well. You should play Lost Odyssey if you haven't (it's on 360), it plays spot on like the old school FF games including random battles. Great RPG.
I wouldn't overlook FF15 though if I were you, just have to understand what it is doing and if you can do that the game looks great.
