Last updated: Friday, January 10 2025 A fun added aspect of Persona 5 Royal edition is the card game "Tycoon", which you can play against the AI. It's also a perfectly reasonable real-life card game, playable with a 52 or 54 card deck. The precise rules aren't very well written anywhere, tho, and I'm regularly forgetting small details, so I'll compile here the complete Tycoon rules as I know them.
