This server is called Nation States and it is a new semi vanilla world that uses the towny claiming system. When I joined it felt like the whole point was to build nations and not just random bases.
The server wants players to focus on roleplay lore and conflicts. That means people are expected to act like they are part of a real nation. You are supposed to do diplomacy trade and even war with other players.
There is something they call the spirit of the server. It is about having fun roleplay good lore and actual conflicts between groups. If you ignore that and just try to ruin the experience they will remove you to protect the server.
The theme is early antiquity so it feels like a really old world style. The map is a custom map that is about 5k by 5k so it is big but not too huge. It makes nations feel close enough to meet and fight.
You can join from Java Bedrock and even console so a lot of people can play together no matter what device they use.
