This.  For those that played past Persona games, either 3 or 4 you didn't have so many stop and start moments to get past a specific area.  Once you decided to do a dungeon or set of floors in either P3 or P4 you could push through them in one go.  I'd add that the game in general is too long for its own good, especially towards the end where it just felt like filler to prolong the game.  There weren't as many special or fun moments like in P4 either.  

I think P5 would have been noticeably better paced without Momentos at the very least.

Exactly. Mementos sucks. I think they put it in there ti please past Persona fans of older dungeons but it just felt needed. I liked Strikers a lot since being action orented things go a lot faster. not claiming it to be a better game. Just the dungeons are nicer to me.

Persona 3 FES.

For 6, I'm hoping for a more open world game inside and outside of dungeons. Less, and faster load times. Expecting this to release on PS5/PS4. Would be nice if it released on PC as well though.

It's 5 for sure.

Bonus: If it can live up to 5 that would be more than enough. I expect it will be on PS5, but maybe also on Switch or it's follow up if they don't have an exclusive deal. Hell maybe even PC if we're lucky.

Fire Emblem Three Houses

It would make a lot of sense. 3 is pretty much the first modern Persona game. And as I said, the most modern thing to play it on right now is a PS3 or Vita. 

It would really be a smart business move to at least port it to PS4/PS5 (and possibly Windows or Switch). Or it would be smart to remake it.

Let me make it quite clear I have no favourites they are my family, but having said that Persona 4/G is the child that shows Daddy the most love and affection and will inherit the family fortune, now onto the bonus question, I'm most looking forward to Persona 6 showing the other children that following P4's* lead by showing me more affection than their mother is not only the way to my heart but leads to my Will, the second part of the bonus question regarding platforms is the Vita.

* denotes affectionate nickname.

I like Persona 4 and 5, but if I had to choose, it would be 5.

Out of the mainline games I've only played P4G so that.

Only played P4G and P5, love them both but P5 is better.
