You can micro-manage tactics, shown above is one type of intercept option.
Play by email is fully supported and well suits the chess-like nature of the game. It is turn -based with events unfolding in real time once both sides have entered their decisions. You can zoom in and out on the action. You can set up for a 1 day event or elect to play out the whole 6 weeek campaign. Based on the reputation of Grigsby this will be good value for the board game crowd.
