This server is called PGMC World and it has three different ways to play. You can join a survival server, a creative server, or a vanilla server and switch between them with simple commands.
It is made for people who like to pick their own playstyle. Some players can grind and survive while others just build in creative. If you want the simple classic game you can stay in vanilla.
The server also uses a hub style so you can move between the survival, creative, and vanilla worlds. It feels like one place with three different vibes so you can do what you feel like that day.
