Militarium started out life as a board game, this was done to allow for rapid iteration of basic combat mechanics as well as deciding on a good win condition.
Players would take alternating turns spending their money to place Bases and Influence. Like Go, bases could be placed anywhere on the map, while influence must be connected to a base. In addition to the surrounding mechanic of Go, players could engage in combat by "flanking" their opponents all the while fighting over key resource and victory locations.
The game often results in an almost beautiful board state, lasting about 15 - 20 minutes. This prototype was done in a smaller group as both a proof of concept and a pitching aid.
