1. No stonefall traps, very limited use of cage traps.
2. Minimal weapon traps(usually no more than 1 line), and those weapon traps can only contain one weapon each, and must be a specialty trap component weapon. Just enough to keep pesky wildlife out that shouldn't be inclined to enter such a structure anyway, but not be a real threat to a siege or ambush.
3. Never completely seal up the fortress, there is always a 'not guaranteed death' way in. Large deathtraps count as guaranteed death. Having to fight my army does not, even if the goblins disagree.
4. Invader junk is just that, junk. Cloth and leather goblin gear will be magma'd or atom smashed, never used or sold. Metal gear must be melted down, and reforged. Those () are impure. The map is also to be kept relatively clean of litter. A few objects here or there are fine, but large piles of garbage need cleaned up.
5. No intentional non-hostile sentient deaths. This includes unreasonable nobles, and elven traders. Also all attempts will be made to meet room, mandate and demand requirements. And tree cutting limits will be adhered to when feasible, and goods will not be siezed. This does not however extend to protection, the military will not go out of their way to save either elf or noble during sieges or ambushes.
6. No runesmith editing with the intention of the fort surviving. (no editing moods away, no stat enhancements, no resurrection, etc. However zombifying half the fortress and watching the show before abandon is fine.)
7. No savescumming.
8. Limited crossbow use. For every 1 crossbow military, there must be 2 melee military.
9. Chief medic gets an office. Planned to be enforced with modding in the future.
And a few imposed by modding that I have been dealing with in every fort for years that might as well be included.
1. [CARNIVORE] No farming for food, no cooking booze or seeds(carnivores can't eat any prepared meals)
2. More than 1 invading civ. (goblins and orcs currently. Used to include a short stint with Rapax as well)
