This is a typical Minecraft survival server, but you are able to go into spectator mode!
It also has unique villager shops with good trades.
There is also a separate PvP arena, where you are allowed to bring your own stuff!
You are able to join this server in VR! Goto http://www.vivecraft.org/ for more info.
