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.
Technically, my first was P3. But I don’t really count that as I think I only made it through the May. I count Devil Survivor Overclocked, which was just so much fun. I want to finish it but I’m stuck on a boss and now can’t really justify pulling out the 3DS to play it. Since P5, I’ve been in love with the entire Megaten space and I’ve been slowly working my way through some of the games.
