Yeah, I know. I was mainly joking there, but obviously the most important thing here is that FDev has a server that stores the galactic state and "runs" the BGS. You want two galaxies, you need to have two galaxy databases running side by side.There are servers but the matchmaking server does exactly that and nothing else.
Checks what instances are running, checks the matchmaking rules (mode, wings, friends, blocks, etc.) and then either starts a new instance with you as the host or places you in a shared instance that someone else is hosting.
