>>2067731Ok i'll explain, they can do what Westwood did and just say that Emperor declared War of Assassins over Arrakis for houses interested in taking control over it, who harvests the most spice or destroys forces of other houses will rule the dunes, but there's a set of rules they must follow as well as Great Convention, houses are permitted to warfare only on the Arrakis and can use only conventional weapons, i.e. no lasguns or shields. But as fight goes on it becomes quite obvious that Emperor started this whole thing to either weaken or outright destroy houses that got involved because they grew way to powerful to his liking. And so, houses start bending the rules or outright ignoring them, deploying more and more up-to-date weapons also some new stuff they invented. The Emperor might also show favoritism to some houses, for his own amusement or out of desperation, sending Sardaukars in disguise or openly, depending on how close the players house to total victory, which is deposing the deceitful Emperor and destroying the last remaining house that Emperor sided with in hopes of winning
