Hiya!
Picked "Every Adventure" first...then thought about it. Nope...VERY close to 100%, higher than 90% but that was the closest.
I tend towards using some old adventure I have or one I've written; typically BX/BECMI/1e/2e adventures. Then I "start them" and after that initial 5 to 10 minutes they sort of take on a direction unto themselves. Seeing as I, and my players, absolutely
LOVE underground adventures...even when we aren't playing D&D!...they almost always end up heading towards some dungeon, cave system, ruin, etc. But, on occasion, rarely, they have decided to do a more "overland adventure" thing. Like escort duty for a merchant's family, or maybe a special delivery task, or mapping the coastline of a newly discovered island, etc. Still, those often end up with the PC's actively hunting for dark places to venture into!
I think the ONLY RPG system where they do the exact opposite (avoid all dark places) is Call of Cthulhu. Huh...no idea why though...
