IME, Pathfinder Society is the opposite of casual gaming. It's the closest thing we have to Esports in the TTRPG hobby.Isnt this what Adventurers League is though? Pathfinder Society?
All details must be meticulously submitted to Paizo by the GM. Players must track every gold piece earned or spent. There is little wiggle room for any rules misinterpretation or on-the-fly decision - a GM could lose the "privilege" of running Society events if reported. The most involved players have binders of characters, each made with the most competitive builds designed to "win" the scenarios. They boast experience with the replayable adventures and "guide" newer players through them - pointing out hidden traps and monsters.
For me, running a Society event (which I've done several times) is the vilest bastardization of the RPG experience, a joyless and soulless experience that requires the GM to be an rules automaton - a game golem.
