CaliCraft is a player run server based out of California where the whole point is that players can shape what happens. Every two weeks everyone elects an Emperor and that person can actually change a lot. They can add or remove plugins across gamemodes and make laws and even imprison people. If you get marked as a fugitive you can end up spawning in prison when you die or get dragged back in handcuffs if someone catches you.

The server has a lobby so you can jump into different gamemodes fast. There is Modded Survival with custom enchantments and skills and jobs and an auction house economy. It also has custom dungeons and vote crates with strong gear and it is a claim world with a kingdom run by the Emperor.

There is also Vanilla Survival with quests and chest sorting and daily rewards. There is Skyblock with classic island play plus addons. There is a Cobblemon mode where you catch train and battle Pokemon inside Minecraft and it runs on a separate Fabric server so you need the Cobblemon modpack installed.

They also use a custom resource pack with unique mobs and animals and elites plus dungeon bosses with special drops. Versions supported are 1.17.1 to 1.21.10 and it works on Java and Bedrock.
