In StarCraft 2, Blizzard like every other corp wanted to see and control everything we do so you have to go all the way through the internet and lag even if you sit right next to each other. lol if the connection goes down!
Even on the PS5 when I hand a visiting guest the throwaway DualSense I have to bump through a clunky UI of choosing a user or "Quick Play" and wait while it spins up a whole new home screen and other crap for them, and then warnings about DLC or whatever in Mortal Kombat etc, just to have a short 2 minute beat-em-up session.
Sigh
