Other megaten games and spinoffs allowed too, but mostly Persona. I've been playing a lot of Persona 3 to try and take my mind off the heat wave (I beat 4 back in July), and it's honestly pretty fun. The dungeons (or rather, dungeon) are way better than the ones in 4, and the story's honestly more compelling, but I'd say the QoL improvements in 4 kinda give it the edge, honestly. Haven't played 5 yet and also have only played SMT 1 on the super fami.
