It's made my top five favorite games of all-time, for sure. Totally gonna get Persona Q and Persona 5, but now I'm playing Persona 3: FES before PQ comes out.
Persona 3 is pretty amazing too. The setting is cooler but the characters are a bit more bland as compared to P4. Still incredible in its own right. Glad you're enjoying it!
I'd buy PQ but apparently its a first person dungeon crawler. Not into those lol.
