Okay guys. I recently have come into a bunch of time. I've been interested in Persona ever since P4A, loved it. I want to see some back story. Where do I start? I currently own P4 on PS2, I had picked it up a while back but didn't have a chance to start it. Should I begin with P3P on PSP? Pick up P3 on PS2? I saw someone saying to go back to P2, but I also see a lot of people saying that Persona really starts at 3...
Help! Your franchise is confusing me :L
If you have Persona 4 on the PS2, you might as well start there. It's an ideal starting point. After that, either pick up Persona 3 FES (on the PS2/PS3) or Persona 3 Portable (on the PSP or Vita)
After that, you may wish to check out Persona 1 and Persona 2 (Innocent Sin first, Eternal Punishment second), but their gameplay is fairly different from Persona 3 and 4. Everyone has their preferences there, tho.
If you're curious, Persona 3 Portable has some gameplay improvements from Persona 4 as well as the option for a female protagonist, but it lacks the animated cutscenes and better presentation of Persona 3 FES.
