The idea is not to use the Tool Cupboard and manage building areas differently. To get there, the idea is to have a Conquest flag (craftable: 1000 wood / 100 cloth).
NOTE : Assume that it is not possible to build without having claimed or conquered territory.
Two uses of the flag:
1 - Claim
By planting its flag on a virgin land of any claim, it activates a timer of 30 minutes (visible on the flag/or icon on UI) If after 30 minutes, no one has conquered the flag (by clicking on it 10 seconds), claimed territory belongs to you.
One claim by both player. No more than one every 30 minutes.
Claims have lifetime. Each claimed territory is valid for 3 days. Each time you spend in your requested area, it reactivated for the duration. If you do not log in for 3 days, anyone can claim your territory even if you’re offline.
2 - Conquest
When connected, the other players can conquer your area by planting a flag of conquest that surperpose (even a little) your requested area. You then have two choices (popup or special icon in the UI):
You agree shared claims and thus allow another player to build his newly acquired area.
You refuse it but you must conquer (remember - cliking) the enemy conquest flag within 30 minutes (default if no answer).
If beyond this half hour the flag was not destroyed, conquering your enemy is validated and sharing a part of your area claimed with you.
No more than one conquest per person per half hour.
What do you think of this idea?
