I try to keep good session notes but I struggle with putting either way too much or way too little. As well as sharing what you do, I'd like to hear how successful you feel your notes are and how happy you are with them.
edit: I mean post-session, not prep
I'll be running Operation Unfathomable soon and I wonder how ready I should be for a party that wants to explore the tunnels that leave the map. I know the player-facing map tries to lead them into the heart of it so I imagine that does some of the heavy lifting. Still, I can imagine parties who want to >!turn SW instead of NE when they enter the tunnels!<, just for the hell of it.
So, I'm curious how many of you had parties that left the map >!in directions other than returning to Fort Enterprise or entering the Odious Uplands!<? Did you prepare anything on those directions, or generate it procedurally? Anyway advice to share based on your experience?
