I began with Persona 2: Innocent Sin.
I skipped Eternal Punishment, as I never had the tools (at the time) to play it.
I thought it was okay at best, but nothing ground breaking. I also never heard about it, nor was I part of any online activities for it.
Years later, I had a friend who wouldn't shut up about Persona 3 Portable, so I largely ignored him for a long time. Years later, I finally picked it up on a sale, and got hooked.
After that, I got Persona 4 Golden for a free PS+ game on the Vita, and after getting every Vita free game possible from PS+, I traded in my hardly used Xbox 360 for a Vita, and had zero regrets.
After that,I found a physical copy Persona 3 FES, and currently have it unplayed in my gaming backlog, but after getting the analysis of the Answer, it'll remain unplayed.
I found Eternal Punishment on the PSN after this, and dabbled in it, but it did not hook me as much as IS did. I also have a ROM of Persona 1, but it did not age will so I'm having issues playing it at all.
Persona 5 jived with me the most when it released, then Mishi made this site.
Woah, I didnt know @Joker is one of them. Cool!
If only I could play P2 and P1
