A semi-vanilla Survival Minecraft Server. Survival game play is where you can die - often by falling damage, monster attacks, drowning... basically from the environment. Your first priority on a survival server is to find shelter - when darkness comes, everything wants to kill you.

A semi-vanilla Creative Minecraft Server. You mainly just build structures. Often free resources is part of this game play and you cannot die from falling, monsters etc.

A Free-For-All Survival PVP Server. Once outside the protected spawn region you must defend yourself from monsters and players alike. You can play alone, in a group or team... just be careful as many can be deceptive. You can do anything but use hacks/glitches/cheats/client-side mods... basically anything that can give you an unfair advantage.

A Skyblock Survival Server. This server will challenge players to live on a floating island and survive with few means. You will need to make cobble generators and infinite water to get started right.
