The Google Play Games App is now on pc but there's only a few games available. The testing is only for certain regions including Australia, Hong Kong, South Korea, Taiwan, and Thailand. The Google Play Games App ports existing mobile game on pc with proper keyboard and mouse control and more mobile games are on the way. Currently the game are only properly optimized in terms of controls, as the controls are currently unconfigurable and for MOBAs that's gonna be a bad thing as MOBAs requires a more precise control for player to properly enjoy the game but there are games that works very well, 1 good example is Sword Art Online: Integral Factor, It has a PC UI and the instructions on the screen are for pc, I say its already in good shape. Another game is Cookierun which I must say, is already a PC game based on my experience, It runs pretty well and I encountered no problem. The Google play store release date will vary among regions.
