You can play any main game you want, they're not really connected. Same structure and officially in the same storyline (I think), a couple of support characters are the same in every game, and you could get a cameo from a past game (there is a small P3 cameo in P4, I don't know for P5). That's it, so you can jump right into P5 without knowing anything about P4. It's not true for some spin-off games though (Persona Q and the fighting games Arena and Ultimax), because those games are P3/P4 crossovers. |
Well, Persona 2 (both versions) have playable characters that were also playable in the first game, so I'd say that playing P1, then P2IS and finally PS2EP would be the best course of action when playing the older games.
