The short of it is that Google is closing down the Chrome Store.
So you soon you will no longer be able to purchase apps at https://chrome.google.com/webstore/category/apps unless you use the chrome operating system (which I think is just for chromebooks).
That means that those of us who like to play Choice of Games on our desktop computers, while offline will be limited to only being able to play at Steam.
BUT Steam has issues for some users, is more expensive than the chrome store, insists on running a background app and updating all the time. AND not all Hosted Games or Choice of Games are released on Steam.
Google does not want out of the app store business. They still have the play store, but that’s only for android apps.
