So less guys with knives and more WH40k Space Marines. Impossibly expensive elites who cannot be equaled by a mortal. Still leaves me questioning how anyone could wage war. If the Harkonens could barely afford it, nobody can. Also wondering if the Guild charges different rates for goods vs military. What is worth the brutal intergalactic shipping prices that you would not develop local industry to create it? Surely nobody is moving grain or ore, yet the Guild ships are portrayed as comically massive.
