Establishing Servers for fortnite in South Africa

Quick Question:
How did servers work on LAN back in the day for example?
-Didn’t the servers work off the end-user via their device?

*Because, could Fortnite set up something similar to where ‘Servers’ are on ‘End-User Devices’? At least for Creative perhaps?
**This will free up server space on AWS and allow for lower ping for people in places that are far away from the AWS servers? At least for creative with max of (8-16) players perhaps?
***Would have to test for the maximum amount of players allowed, I know (100) would be a lot for an end-user device :wink:
