Its a gacha game strategy, which is a type of Japanese vending machine that delivers prizes in an opaque plastic ball.
I recently watched a you tube video of a guy who admitted to spending 600 bucks to get a certain character skin, to play an otherwise ftp game online. He had to continually open loot boxes to get the drop.
I crafted a legendary on a game during the Covid shut down, and there appeared to be a gearing of mechanics toward spending money to make the process go a little faster. The game appeared to be all but shut down in other areas that people would refer to as "the game" to focus on micro-transactions and loot boxing.
This explains the gacha mechanics a little.
