Town Mode - New Multiplayer Mode

I have an idea for a new multiplayer mode, i call it the Town mode. The idea is You can only choose one world to be your Town world It must be survival, achievements on, and never hardcore This will be your permanent Town world Your friends from their own Town world, could join your Town world from the pause menu, bringing with them their inventory. When they join your Town world, they will stay on a Waiting Room that you can customize for them with recourses from your world Once there, based on your crafting recipies, they can't bring certain items you can't craft or you don't obtained yet. However, if they bring those items yet, those items will be confiscated until they leave to their worlds You can also add ranks: Visitor: Can only interact with you Helper: Can interact with allowed areas on your world Best Friend: Can interact with the hole world
