I mean it used to be the norm for games to have cheat codes built into them. Maybe you get stuck on one part and need help, maybe you have fun spawning a bunch of weapons and going on a rampage (see GTA), or maybe you just want to see what happens if you spawn a giant enemy in a small room.

I once worked with a guy who would actively remove everyone else’s comments any time he touched someone else’s code. Only comments he made during code reviews? “Does this comment need to be here?”. The code was a barren, commentless place.
