Factionators is a generally small server suited for all kinds of people, it has 4 worlds and also the hub.
The first and original world of the server (and the cause for the name) is the factions world, it has two or three larger factions, but is always welcoming new ones to ally and fight.
The second world created was the creative server, it has plots that you can allow others to build on, or just let yourself build on.
Hardcore used to be a very popular server when it first came out, as you could respawn but all the mobs were very strong and difficult to kill, hence the name hardcore.
The final and most recent world is skyblock, which is one of the more popular servers, it has a few island styles and types and a couple of larger skyblocks with many players.
Overall the server is a nice community that welcomes all.
