There are countless games that simulate worlds and societies with hierarchical structures (you are a god, you are a military leader, you are a business owner, you are a football club manager, etc). Are there any games that explore player agency within an anarchic context? I'm not asking for examples with mere absence of visible hierarchy (e.g. OpenSuspect) but rather simulations of explicit anarchist dynamics and horizontal structures.

I'm interested less in games that portray anarchy as an unstable state of social unrest (i.e. rioting), but rather as a stable state of being and living for human beings.
