The first RPG Dave ever played was one of his own design (and the first session ended when an unstoppable force met an immovable object).
Since then he has designed Steampunk Crescendo, City in Darkness, InGendarme, Moral Fiber Optic, Legends of Lanasia, Heart of Glass and others.
Dave strives to make compelling settings that are inspiring even without the rules and rules that are fun to play all by themselves.
