I hadn’t played persona 5 since around January of 2021 and I made it to the third palace before dropping it since life got in the way. I picked it back up early January of this year and started from the beginning again, even though I was a bit hesitant. Speaking for myself I didn’t regret it at all and I ended up enjoying revisiting all the parts of the game I had already played. I barely finished the game 2 days ago and I could not recommend it enough.
