I still recall how, as a fresh-faced, young gamer just getting into the newfangled realm of online multiplayer, I got absolutely got in Everquest when somebody told me you could get a numeric representation of your current experience points by typing "/ex".
It was actually short for "/exit". And in those days, it took a loooooooooooooooooong time to relaunch the game and get logged back in. Learned a valuable lesson about human nature that day. It has served me well.
I got people with ‘/qui gon jinn’ in Jedi Outcast and Jedi Academy.
It runs ln the Quake 3 engine, so it would just ignore everything after the space and auto complete the closest command, which was ‘/quit’ which instantly quit the game.
I got so many people because it seems like a plausible cheat code in a Star Wars game.
