SCENE DYNAMICS ENGINE for when PLAYERS MUST COMPLETE A CHALLENGE.
So... I play solo and try to make things simple and quick. No prep. No spoilers. I made an engine that allows me to process any action or dramatic scene in a way that every roll produces a playable result. Every roll expands and then the MD contracts the answer that is applicable in context or implication. It works for convincing the Emperor, running away from a mob or trying to save a kitten from a tree before the dragon lands. Every roll should only be done at he last possible moment. This is my first post so I have no idea how the formatting works.

If anybody needs any help in understanding, I can take out the dice and generate some examples. One must understand that this engine is only that. An engine. Fuel, grease, spare parts etc. are up to the player. Use any and all means to simulate the rolls. Expand and contract. Imagination. And DC checks when appropriate.
