Something interesting I learned last night...

...about world-building, and more specifically running a game in a world which you haven't set down entirely on paper yet.

In the absence of evidence to the contrary (typically, this means formally-codified setting information), players will assume that your world is like the worlds with which they're familiar.

I ran into this several times during last night's game - on topics varying as widely as the existence of guilds (there aren't any in Darán), salvage rights (which I haven't actually codified yet), and gambling (card games don't exist - the only "playing cards" are fortune-telling devices similar to Tarot).

Something for me to keep in mind, anyway.
