I have a 1.13 server: "Vundervorld"
It's a pretty fresh map started shortly after 1.13 dropped with tons of ocean & lots of rare biomes all within 2-3K of spawn.
Right now it's just me and a handful of other players. We're not looking to have a huge hectic server, but it would be fun if there were 3-6 people online at any given time instead of 0-4 like it is currently. The server is hosted in US but we also have European players.
Pretty basic rules: No cheats, no griefing, don't be a jerk. Mature players only.
This server is vanilla, but there are a few modified features via datapacks, gamerules & command blocks.
Only one player has to be in bed to pass the night cycle.
Loot for certain treasure chests has been modified to be more rewarding.
Loot from fishing has been nerfed. Basically all you can get from fishing now is: cod, salmon, lily pads, seagrass, kelp, string, sticks, and damaged fishing rods (sometimes with low level enchantments).
Game coordinates have been hidden to encourage using maps & compasses and to make the game more challenging & immersive.
Each player has the option to choose a single 250 block radius (500x500 circle) of protected territory where all guests will be in adventure mode.
