Of course we start this off really hard, but I'm giving it to Nocturne. P5 is a fantastic game, but it's too soon for me to say if it's even the best Persona game for me, whereas Nocturne slipped into my top ten favorite games of all time without me noticing. P5 might have the better emotional payoff, but Nocturne has the deeper gameplay and the more thought provoking plot.
