I would like to see a game where your troops and movements are not seen by other players until they decide to attack that area. The only indication of ownership would be a (X) or other symbol of your color on the map. Your placement of new troops would also be kept in the dark.
The only messages broadcast would be the normal who took what from whom.
Teams would be able to see their own teams.
Cards: If you hold the card of an opponents territory you can see the troop count.
