Krafton (formerly Bluehole) subsidiary PUBG Corporation, saw its main game generate $920 million USD in revenue last year with $310 million USD of that being profit. 53% of that revenue came from Asia.
What is more impressive is that $790 million of that revenue came from the PC version (console made up $60 million). Really not bad for a title that wasn’t even expected to be this successful.
