Iperios is an SMP where you can make your own nation and pick how it works. You can set up your own government with laws and ranks. If you do not want to run things you can join a nation that already exists.
The big thing here is geopolitics and wars. You level up McMMO skills and use them when your nation fights. There are resource camps in game that nations can conquer. Those give geopolitical resources that help your nation expand. There are also lots of resources and buildings you can create and the server has active support.
The server uses Dynmap plus McMMO and Essentials. It also has GriefPrevention and SilkSpawner. There are custom enchants with ExcellentEnchants.
To play you have to get whitelisted first. After that a staff member helps you start and gives you a beginner kit.
