Eden is a Minecraft server that is trying something different. The world is meant to be permanent and it does not wipe when people get bored. Your builds are supposed to last and the server has tools and special mechanics to help protect your land.
The world is tough because resources are scarce. Farming is also more challenging because crops are locked to certain biomes. There are industrial factories too so players can build bigger systems and not just small bases.
What makes it feel alive is that admins do not force events. Players make the wars and the political deals and the trade networks by themselves. The world map and the wiki are kept up by the community. There is even a custom printing press factory so players can publish books about their faction lore and laws and religions and it all gets archived on the wiki.
It feels like a big real time fictional universe made by the players and it wants more people to jump in and leave a mark.
