Sorry, but this is disingenuous. Valid criticism is not "insulting". Additionally I've already watched that video. That developer purposefully made an extremely niche product that only a fraction of people wanted and was able to make a living doing that.
Which... proves my point. His games don't have mass appeal at all, so they don't make money.
I've been through the Switch catalog. There is so much trash on there that it's unbelievable. In fact, most people will agree that these App Stores are chock full of garbage games. I get ads for garbage mobile games on my Instagram feed all the time.
Making a playable game and making a good game are two different things. Most games are simply not good games.
Edit: I'd argue that you can't give me a good example because they don't exist. If there was a game you truly loved that was an underrated gem, you'd be super quick to show it. And that's what I'm trying to say: this concept of a polished, good game that is inundated and skipped on by the sheer amount of volume of good games, in my view, simply doesn't exist.
