I have been an admin of a server from 2013-2017.

I'm thinking of starting a new server, but I need some input..

I have ALWAYS used vanilla servers. No plugins that gives an advantage over another player. Only anti-grief and one-sleep. Make the world a better place.

With that in mind, I've been thinking about these scenarios:

1. A world in a void, (like skyblock) but all biomes are included. So you can get mobs, guardians, and everything else. I've seen them making it on YT.

2. A normal world, but it is ALWAYS day/night. So either way, you have to be ready for each scenario.

3. A full void world, but everyone has creative mode. So It's sort of "create your own world". Either that or do it on a super flat world.

4. Make a cave world, and make everybody live underground indefinitely.

Any other ideas are welcome, that puts us off the edge from other servers. While still keeping it vanilla.
