The company didn’t provide in-depth details on how the Android games will be able to run natively on Windows via the app. That being said, Google promised that gamers will be able to seamlessly switch between Android phones and tablets as well as Chromebooks and Windows PCs.
This is not only in terms of catalogue access but also the ability to resume Android game sessions on Windows machines and vice versa. Furthermore, the games will run natively on Windows and not via cloud streaming.
Meanwhile, there are no words at the moment whether Google will eventually bring the whole Google Play to Windows. Nevertheless, having a native Google Play Games app seems like a great start. (Source: Android Police.)
