I found a new Java server on 1.21.10 that is going for a super close to vanilla feel but still has a few small mods like enhancements and stuff that lets you set a home.
The whole point is anarchy style fighting with clans. People can start wars make deals and try to take over. There are no land claims so nobody is protected by fake borders and you can raid and battle anywhere.
You can build an empire if you can defend it. Dying matters because keep inventory is never on. You can also collect player heads as trophies and take their gear.
The staff is active and fair and they watch for cheating. Hacks like x ray are not allowed at all.
Ruthless Clan Wars Vanilla Anarchy
GG.MINEWIND.NET New Server IPMaboro-Light Adult Vanilla SMP
This server is called Maboro Light and it is a vanilla style SMP with a big world that is 20k by 20k blocks. It runs on Minecraft version 1.21.11 so it is pretty up to date.
The gameplay is mostly pure survival but there are some small plugins and datapacks that make it feel nicer. There is proximity chat so you can talk to people only when you are close to them in game. There is also a plugin to protect your builds so random players cannot just break your stuff.
For extra fun there are datapacks where all mobs drop their heads and players also drop their heads when they die. So you can collect heads and make little trophy rooms or just mess around with them.
The community is Arabic but they welcome anyone who is 18 or older. It feels like a chill adult server where people want to explore and build and just hang out in survival without crazy mods.GG.MINEWIND.NET New Server IP
