If there's one game that needs no introduction, it's Genshin Impact. HoYoverse's free-to-play action RPG took the gaming world by storm when it made its debut in September 2020. Despite some mixed pre-release reception, it ended up generating a shocking $3.8 billion in revenue by the end of 2022, making it the most successful first year on the market for any game ever made. What made Genshin Impact's launch even more impressive, though, was that it accomplished that when it wasn't playable on all platforms. When the game initially came out, it was only playable on PlayStation 4, iOS, Android, and Windows PCs, with no Xbox and Switch versions available.
