I found a public ATM 10 server that started as a friends server but now it is open to everyone.
The big idea is letting people play how they want. You can team up and make a nation with rules and laws or you can travel thousands of blocks away and live alone.
There are rules but they are just the normal basic ones you would expect. The server also has basic commands like home back and tpa so getting around is easier.
If you have questions the owner says you can ask and they will try to respond.
Kings Talk is a fantasy modded nations roleplay server where players can start their own nation or join one that already exists. You can make original roleplay characters and basically do what you want with the world.
The nations grow in an organic way and the modpack has RTS style units plus siege weapons and automation. It feels like you are building up a civilization then deciding if you want peace or full on war.
The map is 3k by 3k and the server stays running all the time. It is Java 1.20.1 and it is modded with organic RP nations and voice chat.
Meraki SMP is a survival world that feels like it is built by the players. People can make towns and grow them together and the world is meant to change over time based on what everyone does.
It supports Java and Bedrock crossplay so you can join on the version you like. The terrain is custom made with Terra so exploring is actually worth it and the views look wild.
The server uses Towny for town building and there is an economy that is meant to stay balanced and evolve. Politics are optional so you can do diplomacy and trade and alliances without it turning into forced PvP.
There is also BlueMap so you can look at the world from above and there is the Brewery Project if you want deeper crafting with drinks. The server is launching Friday so early players can help shape everything from the start.
AeternalCiv is a geopolitical civilization building server where players write the story. You can be a citizen or a king or queen or just a hermit and do your own thing.
It has reinforcement with Citadel and snitch mod so land and bases feel more protected and politics can get real. It also runs Slimefun and Origins plus Brewery and ValhallaMMO.
There are seasons and levelled mobs with RPG mechanics. There are custom recipes too and more changes are planned since the server is still in active development.
It started as a small server for four friends and now they want more people to build nations and make an Aeternal destiny together.
Worldbound SMP is a geopolitical survival server where the world is still pretty empty and new nations are just starting to form.
Players can create or join nations then build cities and capitals and set up borders as the map fills in with real player history.
The server uses a satellite style world map so the continents and oceans feel more realistic when you explore and pick where to build.
It has alliances and diplomacy and also nation wars so the map can change a lot depending on who teams up and who fights.
It supports crossplay on Java and Bedrock and it runs on version 1.21.11+.
LilacMC is a Towny survival server that is trying to be fun and friendly for everyone. It has Towny and mcMMO plus other core features and also custom stuff made just for this server.
The economy is player driven so the community sets the prices and there are no admin shops. The world is almost 5 years old and it has never reset and they do not plan to reset it.
There are custom features like Lilac Saplings with over 200 custom trees for decorating. There are also Lilac Mob Arenas with different difficulties plus buffs and debuffs and challenges and maps. The server also has custom farming fishing and mining to keep endgame players busy.
It supports versions 1.21.4 to 1.21.11.
This is a Bedrock server where the players shape everything. The world laws history and conflicts all get made by the community.
You can try to be a fair ruler or go full dictator. You can also reject kingdoms and play as a militant that fights everyone.
It is welcoming if you only play about one hour a day or if you grind way more. The server also uses add ons to change up the experience.
This server is a worldbuilding project where people make nations and push the story together. It supports both Java and Bedrock and it has an active community.
The main feature is Movecraft so players can build ships tanks and planes out of blocks and actually use them. It also has Brewery X plus lands a market an auction house a stock market guns seazones and more.
It is not only about fighting even with all the vehicles and guns. The focus is building lore and watching the server story grow through the community. There is also an international news channel vibe where you can keep up with what is happening.
The server recently reopened after a dev break and it is meant to give space for new players and new nations to join. You can make your own nation and try to make history or join an existing group.
Cosmix World is a fresh SMP server where players make nations and try to survive the wars and drama that come with it. You can start a town then grow it into something bigger and try to make your own history.
