https://www.extremecraft.net/This server is honestly one I've been enjoying playing on for about a week or so.
It offers many different ways to play the game. Anywhere from 300-1000+ people on the server at any given time.
But their OPSurvival mode is the best close to original minecraft I have played in a while. People cant easily grief your base as long as you claim it properly, and you can still pvp if you run into people in the wild.
The server is running many popular plugins that people should be familiar with such as combat log, grief prevention, crates, quests, bosses, ect , running 1.8.9
Come join me in game and say whats up, IGN TheNyne
