It would be great to be able to have a main world and sub-worlds linked to the main one.
The subworld instance would only be reachable through the main world. The SubWorld playercount would count towards the playercount of the Main World.
The world and all it's sub-worlds would appear in the menu as a single world.
It would all count as a single "Game".
For Example : People can join a "Golf World" that is essentially just the lobby, before accessing a subworld within the "Golf World" that would be one of the many available courses.
Example 2 : This would allow a "Murder" game world to have multiple demanding maps that you can switch inbetween by "switching worlds".
This would be made to allow worlds to reach a bigger scale without compromising on optimization. It is currently possible for people to go from world to world, but this obviously reduces the playercount of the main world.
Roblox currently has this functionality and i think we could use something similar for ambitious world creators.
I feel this is important to support bigger game projects within VRChat without lowering their playercount.
