Whatever Atlus’ next game after Metaphor: ReFantazio is going to be, it needs to leave the overused calendar system behind. First instituted in Shin Megami Tensei, an adapted version of the calendar system soon became a staple of the Persona series. It works by dividing the game into days, each of which has its own weather, special events, and side activities. Days don’t progress in real-time, like in most other RPGs – instead, each day is further subdivided into an afternoon and a night, and players may select activities to occupy each and advance the calendar another day.
