If you use the App Store the way the people run them want you to (browse instead of using the search that they hide in a corner) you will find it is already 99% slop. I make a point to only install an app by name if I know the brand (e.g. McDonald's or Taco Bell) or if it is something really famous (e.g. Arknights, Fate Grand/Order)
If you just go looking for a "game" I'm certain whatever you find won't be fun at all.
