I am building a fortress that I may eventually want to revisit in adventure mode. If I abandon with my fortress sealed up against a siege, I would like to be able to enter my sealed fortress as an adventurer.
I was planning on putting a drawbridge opening lever on the outside of my fortress to allow me to enter, but then I had the horrible thought: what if goblins can use levers?
If I put a lever on the outside of my fortress to open my front door, am I opening up myself for more fun than normal during a siege?
This question has been asked for Minecraft, but not Dwarf Fortress.
