WorldBound SMP is a serious geopolitical server where players make nations and try to grow them over time.
It uses a high quality Earth map made with real satellite imagery so the mountains rivers and coastlines look like the real world and every continent feels familiar.
You can build cities castles and big empires then make alliances or enemies and fight wars to take territory. Players also set up economies and trade routes and the politics are driven by diplomacy and what people decide to do.
It is a huge world with room for more nations and the community is active so stuff is always happening and history is written by the players.
