“Intensifying stories” is an attempt to identify what can make a story (feature, capability) more potent.
I’ve identified key features in a number of systems (perhaps 50), identified a rule or concept beneath those features, then generalized that to apply to a number of other systems.

This is no master list (nor do I expect any to exist), but I hope this list is helpful for people working to create highly-valuable capabilities in systems.
