This server is called PGMC World and it has three different ways to play. You can go on a survival server if you want the normal Minecraft adventure. You can go on a creative server if you just want to build with no limits. You can also go on a vanilla server if you like the game with no extra stuff.
You switch between the modes with simple commands like server survival server creative and server vanilla. It feels easy to understand and you can just pick what you are in the mood for.
From what I can see the server is made for people who like classic Minecraft. You can grind in survival or experiment in creative or stay pure in vanilla. It seems like a good spot if you want choices but still want everything to stay close to normal Minecraft.
