if you're going to reduce it to that, we ultimately can go back to the 90's and consider all video games as a useless waste of time that corrupts the mind.

Ultimately, you figure out why games are fun for yourself and focus in on that, be it gameplay, story, charactters, art direction, or simply comfort (I'm sure I can find a few friends who easily threw X000 hours into Stardew Valley). I don't like competitive FPS, but people have made friends, professions, and entertainment just around watching other people play those games. Let alone their own personal experience.

>The worst is when some title is succesful and they get money and they make a sequel that's thrice as big.

that's simply consumer demand, and despite that meme most people are not asking for shorter games with worse graphics made by people who are paid more to work less. Fortunately, games are diverse and you can definitely tailor to your needs unless you must have AAA graphics for your presentation. There are thousands of indies released yearly, but maybe a hundred AAA on a good year spread across a dozen genres.
