From Wiki about their storefront that serves PCs as well:
In April 2017, Tencent unveiled its own flagship gaming platform, WeGame which will host games, content, and services from all over the world and will provide gaming info, purchases, downloads, live streaming and community services, creating an open ecosystem for gaming. WeGame is an upgraded version of TGP (Tencent Games Platform) that already has more than 200 million active users (compared to Steam's 125 million) and over 4.5 billion downloads. It will be dedicated to both global developers and players, and will assist developers who require help with translation. The gaming platform will support both Chinese and global users through a single storefront and is due to go online on 1 September 2017, Tencent has stated that the platform will focus on PC and standalone games and will no longer host web or mobile games, and will provide support to small and indie companies. Aside from mainstream games, the company has promised to also launch titles which include Stardew Valley, Rocket League, Portal Knights, Minecraft, Cities: Skylines, with 170 games promised by the end of 2017.
