The Persona 5 anime can come off as rushed to those who have played the game because the game's life sim mechanics make it generally slower-paced. The anime goes straight to the main plot a lot faster whereas in the game you have a lot of downtime before the "arcs."

One thing that got cut down a lot is the "Confidants" aspect of the game, where you spend time with (mostly) non-story characters and deepen the MC's bonds with them. This aspect got trimmed down for time in the Persona 3 movies, too.
