Dune Choam and Richese House Expansion

This expansion adds two new houses: CHOAM and the Richese, to the Dune boardgame

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. CHOAM is the largest single source of wealth in the Imperium.
House Richese: House Richese, just like the Ixians, had a well-earned reputation for ingenuity, and created important technological inventions.

This is not a standalone game requires Dune A game of Conquest, Diploamcy & Betrayel to play (that is the 2019 Dune game release and not last year's release  Dune : A game of Conquest and Diplomacy)
