Can devs implement the “Half map” rule into Treaty ? It would make the game mode more fair in this way, stopping some people to rush near your gates before minute 40 ends. In my opinion, the only units that should be allowed to cross the half-map line are the explorers. Also it would prevent the opponent to steal your natural resources (in particular the ones that are close to the half-map line).
Another thing that would be nice is to expand a bit the area within you are allowed to build stuff.
