… Other randomized gaming features

This is a little worrying what it means, as all games rely on randomized things to some degree. Some are just bare necessity (shuffling deck before game of solitaire), some are reasonable game design (boss has 5% chance of dropping a nice piece of gear) and then there’s loot boxes

Not every game relies on randomized things, thats simply untrue, but yes there are levels of it
Not every game probably, but I can’t think of one I’ve played that didn’t have some sort of randomization as a core part
