My son still gets together with his friends. They will bring over their PS4 and connect to his computer monitor in his room and they will play with each other “online” sitting right by each other.
At one point, he’s had four friends over all with PS4s playing against each other on separate displays in the house - thank goodness for wired gigabit Ethernet through the house and a bidirectional gig-e Internet connection that didn’t even blink at the traffic. My wife and I were still able to watch DirecTVNow....
Back in the day, they would have to drag desktop computers, CRT monitors and known how to network them for LAN parties.
