The fact is, they WANT you to have to go out and spend more money on games.
I despise Windiws 10. It won’t play Empire Earth. IMO, EE is the best computer game ever made.
MS wants you to use games it runs on your browser, which opens to the Internet, which makes you Internet connected (whether the game is playing others “live” or not) and being Internet connected MS is tracking you just as Google is. THAT’s why they do it, and that’s why they do things like the “cloud”. It is not your convenience that interests them, it’s your trackability and access (in the cloud) to your stuff that they seek to gain awareness of - awareness for THEIR purposes.
I used to play, and love, the game “Double Trouble” — the original, not the revised version. Can’t find it anywhere!!
