Used to a play a server called Civcraft that was persistent for several years - server-side plugins enabled preservation of structures (to an extent) through reinforcement (Citadel), culling of mobs using "Mustercull", biome-specific farming with RealisticBiomes, and an imprisonment system (PrisonPearl) which gave players the power to ban others from the server.

People naturally formed their own laws, governments, societies, and over the years the balance of power went from a fractal multipolar world to a massive "red vs. blue" cold war with minimal conflict. Quite interesting really. Not to mention the massive international infrastructure works, including rails, bridges, tunnels, massive towns, and lag-inducing automated farms.
