I'll be happy to oblige . Britannia is a game for 3-5 players. Each player represents a number of races which established themselves on the British Isles. The control of land is the way people score most of their points in the game. Not all land has an inherent value to all races.
Every race has a point card which indicates what property they score points for and when.
People also get points by killing Romans, destroying Roman forts, and raiding. In addition to scoring points, land is also important because it provides you with new units. For multiple of 3 areas you control, your race receives a new army. Fractions ae retained, so even a race controlling only 1 space will have a chance to expand. This expansion obviously leads to combat.
