The Ghost of Tsushima
There are some similarities, but otherwise they're very different imo - the only things in common are the demons/personas as well as certain skills and elements. Lunar phases can be found in mainline, Persona and other spinoffs, but it works very differently depending on the game. Social Links/Confidants and the calendar system are exclusive to later Persona entries (P3/P4/P5). In most SMT titles (and P1/P2/P5), demons are gained through negotiation, while new personas in P3 and P4 are gained through shuffle time. The Persona series also lacks the alignment routes (Law/Chaos/Neutral) found in most SMT games.I know they're from the same developers but how similar is the gameplay between these and the Persona series?
In short, the similarities only extend to most demons/personas, skills and elements.
