To a point, that can be true… if it’s self-imposed. In my last job, I tried to game-ify some things for my own amusement. It was a small shop, and we had to work alone for much of our shifts, and when it got slow, I’d set challenges for myself.
But when it’s imposed on you, it’s not always fun, or a help to productivity. The bosses started a checklist of tasks to be done on every shift, and if something came up that meant we didn’t get a lot of it done, we should write why. I figured, if they want to know what I do on a shift, I’ll oblige. New game: how many things can I list? 
After a week or so, I got feedback from the bosses. “Sure, we appreciate how much you do, but you don’t have to list everything…” Turns out they were more concerned about other shifts where things weren’t always getting done.
But it was fun while it lasted… at least for me.
