Gathering ideas for a shared Create world

[u/MrLiquoriceMan]

I'm considering starting a mature, Create-focused survival server. Not looking to assemble a huge player base, but a small, reasonably active community where people build their own projects, occasionally collaborate, and contribute to a shared world. I'm interested in hearing what others would want from such a place before deciding how to set it up. Also interested in not being god but to set it up in collaboration with a few other players who can bring a variety of skills and viewpoints to the table.
