Funny, I independently arrived at the exact same conclusion. He's incredibly easy to read and predict because every single opinion he holds is based on his ego.
Like for example, when people ask him why he developed his own engine for his games, he'll answer that it's because other devs take shortcuts and he doesn't. But dude, the entire point of not making your own engine or language is not because anyone's lazy, but because it allows you to focus your precious time on more important stuff like the actual gameplay, the story, etc. Maybe then it wouldn't take more than 10 years to release a video game.
If he was honest with himself, he would rightly say he did those things for his own edification. If you have the time and ability. As someone who also cares deeply about his craft and spends more effort than I probably should improving my personal tooling, I'm clearly all for it.
Is it strictly necessary? Most certainly not. I've met equally dedicated and talented individuals who are fine adapting to existing tooling and working around idiosyncrasies rather than improving the tooling. That personally drives me batshit, but I can stomach it if required.
And he likely spent a good portion of those 10 years making sure it had "most pzzles evar" as if the only difference between quantity and quality was spelling.
Having played his game with the "most pzzles evar" I do think many of them are also consistently high quality. That said 10 years for this game does seem excessive.
