MythicMC is a Java-based Minecraft server network offering Anarchy SMP and Sandbox game modes, with RPG, BedWars, and Practice PvP ones coming soon.
The Anarchy SMP mode features a player-driven economy, no land claiming, and allows griefing. The Sandbox modes feature NPCs with custom dialogue that you can build with. Each game mode also supports Simple Voice Chat.
Other features you'll find include crates, cosmetics, seasonal events, and free daily rewards. For more info, updates, and support, visit MythicMC's website.
