Yeah, this is not the first and probably not the last post about the resettlement problem, you know, the AI ressettling everything faster than you can destroy them (as WoC or norsca or wathever you want).
So what to do? I think that if the player or the AI wants to ressettle they will need to stay with the army for around 5 turns (depending if it's a capital or not) and also the army should have 10 or more units, plus the money that already needs to be paid.
This way if the AI wants to ressettle the world, at least it will take them time and will stop them from conquering while they are doing it.
What do you think?
