I'm afraid a similar thing will happen with video games in the next 20 years, mark my words. I remember when you could buy a video game for 60 dollars and keep it forever. You still can, but I would not be surprised if this eventually stopped being the case.

With mobile games, developers are starting to realize that they can get far more money from the addicts who need to play 4 hours a day by throttling gameplay to 20 minutes a day, and forcing them to buy gems in order to bypass the throttle. This could get worse with things like Google Stadia if they decide to monetize their platform in a "pay as you play" sort of model, where you can pay, say, $4.50 for 5 hours of playtime.
