Honestly, the story isn't all that great, especially the 3rd Semester, the plot of which seems yanked straight out of Persona 1 and 2. The whole "nobody remembers" thing is literally the premise of Eternal Punishment. Akechi's role in the plot seems to be a carbon copy of Reiji Kido. Sumire's backstory is the exact same as Naoya Toudou from the Persona 1 manga. The game's too unoriginal.
