Even then, the loot crate model that is heavily present in most games today, pioneered by Valve in TF2, CSGO, DotA2 and slightly modified in Overwatch is based on those gambling addiction mechanisms. Random items, different rarities, etc. It's even more egregious in games like Overwatch because you already paid a nice sum for the game, and it's still asking you for more money, drip feeding you a few items here and there, making it pretty damn hard to get the cosmetics you want in the game you already paid for and should have already if this terrible model didn't exist.
