Libre Galaxy is a Minecraft server built around player-owned worlds called planets. Every player can create up to three full Minecraft worlds, and each planet is automatically protected so only the owner and trusted players can modify it. Because each planet is its own separate world, planet owners can change game rules, edit entities, and more. Planets can be created from multiple templates, including void, superflat, seeds, and pre-made maps, with a focus on a safe and welcoming community, open sharing and collaboration, and preserving Minecraft history by updating and making older maps accessible.
