I stopped playing after Shido's palace, I loved the game to death in the first 50 hours, but the plot really goes down hill after that.
My favorite part of Persona 5 is still the first (Kamoshida) chapter, meeting new people and getting into the school drama really makes it feels unique and memorable. The bond between the characters seems a lot more meaningful and interesting as well. Most new party members in the late game just feels distant and uninteresting at times, Futaba is the only new part member that developed some intereting bond to MC, almost like she is his little sister.
I really would have liked to see a Persona 5 game with just MC, Ryuji, Ann, Futaba and Morgana in the party, instead of adding new memebers we get to see how their bonds strengthen.
Like seriously, did Haru even know Yusuke? did Ann even know Haru??? Seriously these new party members don't even feel like our friends! They showed up so suddenly and then that's really it, they barely get to know and make friends with each other.
What's really disappointing is the story kinda distance itself from the school stuff and start getting into political and business territory after mid game. Which is really not all that interesting and charming.
In my opinion Persona 5 is at its best when it feels personal, warm and small, It's a lot more interesting when it's about school, teachers, students and the relationship between them.
