At this time, it's not clear whether Kingsburg (Third Edition) differs substantially from the second edition, so BGG is creating a listing for this item that will perhaps be merged away in time. In any case, the setting is the same:
Kingsburg: 3rd Edition includes the most updated rulebook and the best expansion modules developed since its 1st edition, such as the Soldier tokens, the Governor cards, and the extra buildings. Furthermore, the artwork and design have been restyled while components have been redesigned.
The realm of Kingsburg is under attack! Monstrous invaders are gathering at the borders, aiming to invade and plunder the realm! Your king has chosen you to take charge of a province on the border; you will manage your province and help defend the realm. To accomplish this, you must influence the King's advisors and the Royal Family to obtain gold, wood, stones, and soldiers to expand and defend your lands. But you are not the only governor seeking the aid of the advisers! The other players also seek to collect the best resources for their own territories.
King Tritus is waiting for you. Will you be able to be the most influent and powerful governor of the realm?
