Apocalyptic Gaming Network (AGN) has been around since 2010, and it's a multi-server Minecraft network with a mix of modded and vanilla worlds. There are 30+ servers to hop between, including some of the big favorite modpacks like Hexxit, Tekkit, Tekxit, RLCraft, The 1.12.2 Pack, and plenty more.
AGN is built around a friendly community, with a pretty dedicated player base and staff that actually like interacting with people. If you enjoy having a place where there's usually something going on, this network gives you a lot of worlds and playstyles to choose from instead of being stuck on just one server.
You'll find a mix of Factions on Voltz, custom GriefPrevention, Towny, economy systems with shops, kits, keys, crates, and vote rewards, plus global chat, mail, and messaging to help keep everyone connected. The network also keeps banned items to a minimum, with each server having fewer than 10, and there's an active plus staff around in game and on
With all the different packs, worlds, and server styles, AGN is a good fit if you want a long-running network with lots to explore and not much hassle getting started.
