Hypothetical rules for B4CB:

https://chiroyce1.github.io/image/?abd9abdef17a198d8d1cae05db50569b.svg

• You start with one large central outpost with 1000 troops.

• Every turn, you select one outpost to build another outpost. The building outpost must have at least 10 troops in it, which will be transferred to the new outpost when it is built.

• You can choose to build a larger outpost with a bigger land claim. This will require 100 troops from the building outpost.

• Outposts can be built anywhere on a landmass that has another outpost on it, as long as the path to the new outpost does not pass through the territory of an enemy outpost. Outposts can also be built anywhere in the building outpost’s territory, even across water or in enemy territory.

• Alternatively, instead of building an outpost, you can attack an enemy outpost. The enemy outpost must be on the same continent as one of your outposts or be within the territory of one of your outposts. If you send more troops into battle than there are at the enemy outpost, the outpost is yours, all the enemy troops are killed and the troops you sent to battle the outpost stay at it.

• Troops can be transferred between outposts as a free action. Transferring follows the same range rules as outpost building and fighting. Troops must be transferred through one outpost at a time, but in any quantity.

• When a central outpost is destroyed, all of that player’s outposts are removed. Last player standing wins.
