That only applies when you work for someone else or your work is defined enough to not even call it creative, and tbh for this kind of things it just goes better when the dev makes the work they think is needed before setting the deadlines just to wrap it up, otherway they end like Cyberpunk 2077 with a glitchy ass game just to please a few people who thinks a date is a big thing, specially in games it shouldn't be that way, renders make take forever for some scenes, the code sometimes will fail over a typo that takes an eternity to find, sometimes theres "nothing wrong" all the way in and you still need to change or delete a whole part of the game because a random bug appears, sometimes things happen not even for devs mistakes, sometimes the updates on the engine changes something that used to work and then suddenly it does't, there are way too many variables on this kind of works, and when the work is done by just one person the challenge is bigger, this isn't a big corporate, is a page where independent devs upload their works.
