The order I played in is kinda goofy. But I started with Persona 5 on Ps4 and got past the first dungeon before my ps4 died.
I gave up on Persona 5 but when smt iii came to the switch I thought I’d give it a try and I fell in love with it. Became a huge smt fan with my favorite probably being IV or then first Devil survivor. Currently playing P4G on my Vita.
SMT III Nocturne. Still the best JRPG of all time, just love that game’s atmosphere and music, sans the random battles.
Then tried P3 took a while to get through. Pretty good but not really that into it.
Then the DDS duology games. Great JRPGs and some of my favorite megaten titles.
Then P4 which was incredible. 2nd fav Megaten title.
By the time P5 came out I kinda outgrew and got burned out on the teen highschool drama social link stuff. Played around 45 hours and stopped. Might come back to it later.
SMT IV and IV:A was decent. Currently playing SMT V and really enjoying it. I really wish they gave the main series the same care as the Persona games, as I prefer the quieter more straightforward approach of those games than following teen gossip and rizzing up virtual waifus.
