Persona has kind of always had bad pacing.Well one thing that they could do is improve upon the pacing of 5 dramatically
And technically, @Panique Atlus did try to resolve the sudden end of P3 with the FES expansion, as you may be aware, but that gained very mixed reviews to say the least. I at least agree with the nature of death. How would you know what happens to your friends after you die, unless there is a heaven or something. Persona has a lot of connections to religion, so actually implying that there is a heaven in Persona isn't that crazy now that I think about it.
Oh yeah, The Answer or something? I read about that but I'm not really that keen on playing what sounds like a couple of very grindy side games just for a little more story. I'll probably end up watching the cutscenes on YouTube.
Thinking of female protagonists, I think it would be cool if P6 pulled a P2 and had a male protagonist for one half and a female protagonist for the second half. (or vice versa) They could each have their own set of social links and the devs wouldn't have to reanimate cutscenes or rewrite social links and parts of the story to accommodate both genders.
