A Simulation of Social Groups Under A Gift Economy

Introduction I enjoy reading about people. Not individuals, but rather cultures, empires, kinship groups, etc. I'm fascinated by the emergent properties of multi-person systems.

How should you and your friends survive and distribute resources?You could grab something nearby, say a shiny quartz pebble and say to your friends: "Okay, this is our currency. If you want something from me give me quartz pebbles in payment and I'll do the same for you." But why bother? You only have a finite number of friends, and it's pretty simple to keep track of who's doing their fair share in making sure your small band survives. If you notice one of your friends napping while the rest of you are off hunting you will make note t
