I found a small geopol style Java server that is going for a medieval times vibe. It uses a bunch of in house plugins so the gameplay feels more like a world with nations and politics.
The map is huge and custom made. It is meant to feel realistic like a real planet with believable geography.
The owner is redoing the server right now and wants a more active community. It sounds like a good place if you like rebuilding a world with other people and watching it grow over time.
