I think Persona 5 can be painful if you don't like story and characters, because I often come across moments in the game that I could spend as long as 3 hours without doing anything meaningful other than social sim mechanics and watching the plot progressing
Plus it is too massive, Royal take me 130 hours to beat with no proper way to speed things up. It took me 5 weeks, playing every day for hours. If you don't absolutely love it you will drop no question.
I gave it a 10/10, but I understand someone who give it a score like 5
