Re: Seeking Pathfinder or D&D 5E
I am running one of each game.
The Secrets of Phandelver is the Starter Box adventure liberally customized to accommodate a dozen players that started out in three separate groups.
My JAGSS game is a bit like the Pathfinder Society. Players/characters come and go, and whoever is around is then sent on expeditions. I've run six expeditions now, with a new one just getting started.
