Genshin Impact has enjoyed the "biggest global launch of a Chinese game ever", according to analysts.
The South China Morning Post reports the free-to-download anime-style adventure, which came out on mobile, PC and PlayStation 4 this week, exploded on Twitch with more than 110,000 concurrent viewers, and has already made millions on app stores.
It's a big project, too. Liu Wei, co-founder of Shanghai-based developer miHoYo, is quoted as saying Genshin Impact had a development and marketing budget of more than $100m.
