The twist in Abyss is that you can run freely by holding down the L2 button, allowing you to take on your enemies from any angle - an entirely new approach for the series. There are also "Fonon Rings" which appear on the battlefield wherever a spell is cast. If you use an attack of the same element as the ring (say, fire) while standing inside it, it will automatically be boosted to a higher power level - which may well add a new layer of strategy to the battles. The rest of the party is controlled by the computer, but you can tweak their skills and behaviors - what spells they can and can't use, the elemental attributes of their attacks, how they should react to enemies. Or you could just plug in a couple of extra controllers and hand them off to your friends - your call.
