The PC version of Monster Hunter: World is no longer for sale in China. Governmental regulators in that country have pulled its license, and the continued operation of the game is not guaranteed.

The Capcom-developed title, which launched in January here in the United States, was licensed by Chinese megacorporation Tencent for sale and operation in that country. It was a marquee title on its newly refreshed WeGame platform, soon to be a global online storefront and potential Steam competitor. But, days after launch, the Chinese government elected to halt the sale of Monster Hunter: World citing non-specific customer complaints.
