Not to double post, but didn't want to add this to further confuse an already edited and re-edited post.
We need to discuss what we would do if someone of us disrespected one of our theoretical alliances and raided or took a town of theirs. Giving back the town is a given (or letting it be taken back if we need to), I think. Is there any way for Kings to give other people money in-game? Somebody proposed using the Trade Hall to do it (I suppose by having the receiver sell a cheap item for the cost of that + the pay)?
Also important - What do we do if someone of us refuses to stop harassing allies or doesn't want to give back cities/money? Can Kings throw people out of the Kingdom?
Kings can give easy quests for gold rewards, like "Claim 1 land. Heres 10000 gold." You're limited on the number of quests you can give out at a time though, I think it depends on kingdom size. I can currently give out 3. I assume once they're completed they let you do more though. Right now I have 3 claim land quests given to some of the people who joined.
And kings can banish parties from a kingdom. Or at least theres a button for it, I haven't tried to banish anyone yet
Oh, to the folks who have those cities in the southwest: I extended the claimed land west a ways, but im low on turns so you guys'll have to finish the connection. Hopefully the cities don't rebel. Also nabbed two more free cities with NPC governors. I left one city (Giantsgard) along the way because it had an election ending tomorrow, and didn't want to rain on their parade. I figure if the player running wins it and elects to remain a free city, we have plenty enough cities as is. If it's still an NPC mayor the next time I wander by I'll nab it.
