It's not just about parenting either. These things are bad for the gaming industry period. Games used to be made with passion and high quality (for what was available at the time). It only benefits the developer and seriously at the expense of all players.
Oh no, the good old days back when
you didn't realize all of the problems with games 'cause your standards were lower, and games were much easier to make because everyone's standards were lower and the technology wasn't there to spend as much money or effort on a game game designers had passion and made games for the art of it.
You're not changing my opinion, a lot of RNG boxes are bad, but they aren't by definition bad, and I certainly don't think they should be made illegal at all.
