The whole idea concerning the flood isn't vitally important I think. it would be just some means to stop villages from spreading without bound. But maybe it could be made so that houses outsice a certain distance from the townhall are just not concidered a part of the village. So the flood isn't really necessary
Then, I think a village should have the option to be free or part of the kingdom, but even if it's free it should be affiliated with the kingdom it's built on. So nobody can build an enemy village somewhere.
Starting in a random village would - in my opinion - require that the player selects a kingdom. But the problem is, what does a new player know about the kingdoms, what they do/want, who's in them? You might end up where you didn't want, and have to try to switch kingdoms. I think starting on main is still better...
For the weapons, I think they should be left to those who improved them. Maybe an option to give them to the town hall for the mayor to deak with.
Repairing weapons might be a good idea, as long as they decay, say, only as fast as houses do.
