Originally posted elsewhere, but it makes more sense here:
In our first game, the characters met and traveled together to the Keep, getting to know each other on the way. Then they interacted with the guards (I've tweaked Bartho to be a secret cultist, and connected to the vandalism at the temple), picked up a few rumours, and then proceeded to the tavern. They were quite taken by the drinking competition, which they lost in hilarious fashion (having a bit of a tense interaction with the local champ), and then went to the inn to sleep. They stayed in the common room and, being cautious adventurers, decided to investigate it thoroughly. One rolled a natural twenty, so I improvised that his character found a clue to some sort of overarching plot (the Cult) in a pouch found beneath a intentionally loosened floorboard. Several party members decided to skip their long rest to keep watch, and eventually they caught Bartho checking the loose floorboard. They questioned him, with one using the suggestion spell, released him, since they still aren;t sure what's up, and made plans to invstigate this temple situation next game.
That was it...and they loved it! Almost all of the story came from them, there was no combat at all aside from one grapple roll to seize Bartho, and by the end they were invested. So, for this group, at least, there was plenty to provide ermergent story, and they only visited three locations!
