It all really depends on the example. I know tons of developers that skip Unity or Unreal because there is a learning curve and they can already render a cube themselves. They think "I just write a model loader" and ship and not realize how many man years of work they are ignoring in all other parts. Input systems across 10+ platforms, graphics APIs across those 10 platforms, physics libraries, post processing library, all the edge cases of importing that took man years to find, gaming networking libraries and on and on.

Of course is their choice and if they enjoy reinventing the wheel good for them. But they'll spend 6 to 18 months working on reproducing some fraction of the features they'd have for free instead of working on what makes their thing unique.

As I said, "there are plenty of times a library or framework is a better choice".

An egregious example of what I'm referring to is what we saw with the left pad library. That always blew my mind because the amount of effort to find a library, learn it, include it, and use it, seemed really high for the functionality. I don't understand why it saw such adoption - I wouldn't even -think- to Google that functionality as a library; I'd just write it (if I was unaware of the string method, which to be fair, I only know of because of the leftpad kerfuffle).

A game engine is an example where learning the framework is assuredly going to be faster; you'd need a better reason to write your own, and as a dev manager I'd be pushing back on it hard (whether it was coming from the devs or the business).

I was excited for Unity's input system rewrite and hoped that it would allow games to put input events on the wire to the opponent/server as soon as they were received, independently of the game loop. I asked the developer about it and he said "no, it only does part of what you want, and input events for some devices are still processed on the main thread anyway." So it seems like I have to wait decades for Unity to catch up with the kind of thing one can hack into love2d in an afternoon.
