[Suggestion] Add roads
Use your builders to improve your Empire’s roads.
Roads come in level 0-10.
Roads level 1+ grant bonuses.
Example Road level 2 might grant +1 kit/ backpack per stage completed.
Roads deteriorate. After X time, they drop by -1 level.
Example Road level 2 might last 3 days before becoming level 1, while Road level 10 lasts 6 hours before becoming level 9.
Like Watchtower, roads would grant all applicable bonus while under construction.
Using a second builder reduces the time to upgrade your Empire’s roads by 50%
