Factual error: The plot's main conceit hinges upon coders, the art department, and the user-end network team constantly working live at the same time in the same room, as well as developers actively writing code, rebooting servers, and chasing players in-game to get rid of problematic players. No real game company could operate this way. Game content patches wouldn't change the network experience, and in-game aesthetic changes like the ones they make in seconds would require weeks if not months of development.
Other mistake: In the frame you can see the girl is playing on a newer Macbook, she is using a wired headset but the headset is not plugged into the laptop, you can also see she is using a wired gaming mouse, and the USB cable is just sitting there not connected to anything. The Macbook is USB-C only and the mouse is USB-A.
