My campaign that starts next week is an East Marches (an inverted Westie).
The danger mostly comes to the players. That makes it a bit of Tower Defense meets West Marches, as I can run it with a single player or the group, dialing the dangers based on who is present, but not changing the narratives.
It's also highly randomized. I have an 80-grid encounter table with a mix of social, exploration (yes, even without leaving their homesteads) and combat.
