I found Iperios and it is a modded server where you can make your own nation. You get to decide your government style and set laws and ranks. If you do not want to make one you can join a nation that already exists.
It runs on All the Mods 10 ATM10 version 6.1. You have to get whitelisted through their Discord first. After you get in a staff member helps you and gives you a beginner kit so you can start playing.
I found a hardcore SMP that is trying to feel like those Minecraft civilization videos but it runs all the time and it is not just a one time event.
It is invite only and the only way new people get in is if someone already inside invites them. This is meant to keep the community active and help avoid trolls.
The server has secret tweaks and mechanics and they do not give you guides. You are supposed to figure things out yourself which makes paying attention really matter.
There is also a built in clan and family system so you do not just show up alone in a hardcore world. You join as part of a group and you end up being part of an ongoing story.
I found this brand new hardcore SMP that is invite only and it is built around groups and civilization growth.
The big thing is you do not just join like normal. Only people who are already inside can invite new players. It is meant to feel like population growth and it helps keep trolls out.
There are secret tweaks and mechanics too. They do not hand you guides so you have to figure stuff out yourself and pay attention.
It also has a clan and family setup so you do not spawn alone in a hardcore world. You join because someone invited you so you start as part of a group and you get pulled into the story with everyone else.
Iperios is a modded server where players can create their own nation and run it how they want. You can set up your own government style and make laws and ranks for your people.
If making a nation sounds like too much you can just join a nation that already exists and be part of their plans.
The server uses All the Mods 10 version 5.4. To join you need to get whitelisted through the discord then a staff member helps you get started and gives you a beginner kit.
