Hostile takeover.. interesting idea. I kind of like it. But i'm not entirely sure.
The premise of the game is that you have control of the Fort, and when you lose it, game over. This would put in place something that states that you can lose control of your Fort and continue playing. Could be a touchy area.
Goblins would likely kill/enslave as many as possible. End game.
However, as previously stated, other more reasonable civilizations would simply oust your government and put theirs in charge.
If this were the case, your nobles would likely be jailed or killed. Your military would be virtually destroyed (or forced to surrender after taking quite a beating).
One major problem with this is the lack of Advanced Siege Tactics. What if you just hole up? You have a steady supply of plump helmets and ample supply of water. They can't starve you out. They can't get in. You can't get traders, but big deal, you'll manage. What now? They can't possibly win or occupy you. This right here makes the whole idea trivial and pointless.
In a thread by the name (i believe) of Digging Enemies, and I think another siege-related thread, I have previously discussed alternative forms of siege that should be implemented. (If i'm up to it later i'll look them up and post links, i'm not up to it right now). With improved siege and a way to storm your fort, they can
actually get in to conquer you, rather than pretending at being big boys outside.
Add in some ideas discussed in
this thread about philosophy being introduced into dwarfen society, and my introduction to Schools of Thought and their effects on dwarf society. I actually do touch on civil war.
This links very closely to some of what I mentioned there, check it out. In the case of an occupying force, the school of thought would be different from what the natives believe. What a human occupying government thinks of the city and daily life will
certainly be different from what the majority of the citizens think. Especially dwarves. Dwarves likely wouldn't take kindly to being occupied. Especially if there were booze restrictions!!! That makes for unhappy dwarfs.
Civil war becomes possible in this situation, whether in the form of simple riots (which would inevitably be dictated by how many dwarves are unhappy and how large the standing army/city guard is in the fort to keep the dwarves in line) or if in the form of secret resistance organized by the player himself.
An occupying army would simply not stand around for it. No weapons, ever. No Brewing, alcohol is rationed out to dwarves. Weapons forging, armor forging, hunting and woodcutting will all be left to humans. Dwarves get passive jobs where they can't be of any harm to anybody. No traps. No active military units, ever. If someone is caught smuggling, hiding contraband, or doing something illegal, punishment by jail time or in severe cases, death.
If noone can be found to blame, harsh sanctions are placed on the dwarves. Less booze, less food, more work. Government would place harsh mandates on the people. Very strict, very harsh, very very demanding mandates, but all reasonable things that could be accomplished by the dwarves (meaning no demanding things that you simply can't make). They would demand immense quarters of unbelievable quality for themselves, while demanding your dwarves live in poverty in meager quarters at best.
Great thinkers would spread ideas, incite anger. They would not stand for it. They would dissent against the government. The government may or may not stand for this. They may jail dissenters. They might limit gatherings of large groups in any place.
It could be interesting, but like the philosophy ideas, imo, to be truly worthwhile it would need dynamic changes and implementations to the way dwarfen society functions, how dwarves act and 'think'.
(All of this, of course, could be variable depending on the occupying force and how their society functions and thinks. Dependent on the school of thought their people use. Some societies may be nicer and more lenient towards the dwarfs, others not so much. Some may live to co-habit with the dwarves inevitably)
The point, however, at this point,
should be to oust the occupying government and regain control of your fort. Inevitably more foreign nobles and soldiers may come to occupy your fort. You stop getting Dwarf Migrants and you begin getting foreign (human) migrants. All of this makes it harder and harder for your dwarves to break free, makes your freedom more challenging. The longer you take, the more your control over your dwarves slowly slips away. Inevitably if you don't do something... if your dwarves fail a revolt, or it simply becomes impossible to break free anymore.... You
lose had fun. Game over.
