The second non-prologue/non-preprologue chapter of this games story feels like all the good parts of various Stephen King novels mashed together into one narrative arc, and the boss fight against said chapters antagonist is a set-piece the game never really tops later.
However, I feel Square really missed an opportunity by not having Elvis, his friends, and the other party members have impromptu group sex in order to re-centre themselves after being traumatised by the horrors of Folie's lair. They could have really broke new ground for the stagnated JRPG genre, but what do I know?
Gameplay-wise, the stacking of an ATB-sytle system on top of the standard fixed-turn brave/default can be pretty overwhelming in terms of complexity, and enemies with padded HP bars to compensate for the ability to fully brave still cause regular battles to drag on at times.
Still, it looks nice when it runs on a good PC, and it's cool they got the Attack On Titan guy to do the music again.
