From GI.biz: “Genshin Impact is not even a year old yet and it has seen incredible success.
Debuting in September 2020, the free-to-play open-world RPG was the biggest international launch for a Chinese game and drove developer MiHoYo’s revenues to almost $800 million by the end of the year — more than double what the company achieved in the previous year.”
