Ok, now that I've tried it I can definitely say that I'm enjoying it more than Q2, P5 Dancing but absolutely less than P5 Strikers. It's more level based than anything, so don't expect any feel of exploration: it's mostly dialogues + battles and occasional breaks for Velvet Room/Customization/retry missions/additional talks to unlock points for the classic skill tree.

When I saw it announced I wish it was the actual fighting game everyone was hoping for, but nope. We'll stick with P4AU until the end. But it's ok, at least they tried with something new, and this game is still overall alright.
