Black Myth Wukong sells 18m units in 2 weeks. DLC on the way.

It's pretty comparable to Red Dead Redemption II - 17 million in 12 days.

I'm pretty sure it's legs will run out long before it reaches lifetime sales of that caliber, but I guess we'll see. PUBG reached 75 mil before it went F2P in large part due to China, but that also had global sucess and longevity on it's side.
