How many GB is Britannia?

0.73 GB

That is less than the typical Simulator game, which needs about 4 GB.

Leave at least 6 GB free: games need headroom to unpack updates.

The figure is the storage Steam lists as required for this game, not a measured download.

Live over a thousand years of Britain’s early history in this epic game of conquest and rule. From the Roman conquest to the William the Conqueror’s Norman invasion, explore the destiny of many nations, and fight to become King.
