I need to go back to Persona 5, I haven't played it in a month. I left off in September.
Persona 5 is a great game, and I like a lot of the changes they made to the P3/4 formula, but I think the biggest failing of the game (for me up to this point) is the Social Links/Confidants. Most of them I just don't care about the same way I did in 3/4.
The highlight of the series for me is still Persona 3, but that's because I picked it up at release and it felt so fresh and unique for a JRPG. Persona 4 is a better game, but by that point I knew what to expect from it. I would say Persona 5 is more enjoyable gameplay wise than either of those two games but the freshness of its gameplay style is long gone. I hope they really change things up for Persona 6.
