Description de l'éditeur :

This expansion adds CHOAM and House Richese, to DUNE: A Game of Conquest, Diplomacy & Betrayal.

CHOAM: The Combine Honnete Ober Advancer Mercantiles controls much of the economic affairs across the cosmos and have a keen interest in Arrakis above and beyond spice production. Because of its control of inter-planetary commerce, CHOAM is the largest single source of wealth in the Imperium. Influence in CHOAM is a major focus of political maneuvering in the Imperium, both to maximize dividends and to also skim profits. 

House Richese: House Richese, just like the Ixians, had a well-earned reputation for ingenuity, and created important technological inventions. After being ousted from governing Arrakis, they are reduced to selling off important creations simply to raise enough funds to continue their efforts to compete.

This expansion also introduces advanced stronghold and leader skill mechanics to help you gain advantages over your rivals.
