This planet functions similarly to the game's lobby in that it provides access to the various menus. You will also be able to view and interact with other players in this realm, making it seem more like a town. You'll have brief objectives to do in this block world, which are typically simply getting to know the game's many different NPCs. If you want to play games, just select the Play menu to discover what's available. You may also go through the Chat menu to discover other games developed by other people.
