I'm bumping this thread, because the other recent Persona 5 threads have had to do with story spoilers and I haven't quite finished.
I made a big push towards the end of the game this weekend. Like 10+ hours, which is a lot of game for me. Up to about 68 hours and I think I'm close, I just finished the Casino and went through the few *hours* of cut scenes that follow. The villain dialogue towards the end of that sequence may be the most hackneyed, awful writing I've seen in a modern game that was trying to be serious, but other than that I still really enjoyed that whole sequence and only partially saw the twist coming. How much play time do I have left at this point if I'm rushing?
I am ready to be done with this so I can move on to some other PS4 games. I've been holding off on Uncharted 2, 3, 4, and Bloodborne until I could fully finish.
At your pace I'm guessing 10-15 hours.
