After seeing positive feedback about Persona 5 I decided to try it myself. But when I went to PS Store there are so many different versions and packs I'm confused which to buy. Across all packages and costume bundles I identified two major ones - Persona 5 and Persona 5 Royal, and also found this question about them: Does Persona 5 Royal have all of Persona 5's DLC? , which suggest they are the same game.
What's the difference between them? Is "Persona 5 Royal" just "Persona 5" with all DLCs?
