Genshin Impact, from Chinese game developers miHoYo, is a (technically) free-to-play open-world action role-playing game for iOS, Android, Windows, and PlayStation 4 that utilizes "gacha" mechanics — a style of game that relies on players spending real-life money to attain items or level up. And boy, are people spending.
Outside of its knack for enticing players to drop cash on random loot boxes (AKA gambling), Genshin Impact offers players a pretty immense open-world experience, especially for a (again, technically) free mobile game.
Gacha mechanics like those integrated into Genshin are far from new, but what separates the game from its insidiously wallet-draining kin is its AAA trappings. Genshin Impact looks and feels like a proper AAA title, not a hastily developed clone designed solely to rake in microtransactions.
