Expectation: "Quake terminal" implies playing Quake, possibly in some Asciinema-type way. Maybe just starting the built-in Quake terminal without the game-play. Reality: a regular terminal that starts in the notch and expands to normal window. I guess it's somehow based on the terminal that was in Quake but that was only really used for issuing quake commands, not really for being a posix-compliant, VT-100 compatible…
I figured this was the natural evolution of “hacking random device to be able to play DOOM” to “hacking the notch on my computer to play Quake.”
