Diablo Immortal, a free-to-play game, has a microtransaction model that allows players to buy Legendary Gems, which are essential for endgame progression. According to calculations, fully gearing up a character can cost around $110,000. The game's monetization system has been criticized for being exploitative, with some arguing that it targets players with addictive tendencies. The game's developer, Activision Blizzard, has not commented on the criticism.
