It would be great to see Persona 6 bring back school clubs, but it can go even further with them than previous games did. While Persona 6's main plot will have to be its main priority, fleshing out the rest of the world in-game will greatly enrich the experience. If the game's going back to a school setting, that will naturally include school clubs and anything associated with them. Letting the protagonist join school clubs is an obvious move. At the same time, Persona 6 can go the extra mile and make sure that its clubs offer more than before.
