The whole concept of "games as a service" has 1 great advantage :
One is the Server,
One is the Client.
And because of serving everything, the Server has the power - the power to withhold, the power to withdraw, the power to incfluence everything the Server has.
Just look at it in terms of power : If you follow this, then the XBRother is nothing but a natural evolution. Of the way to get power over games.
The NEXT step, however, would be, to WITHDRAW everything from the customer which enables the customer to be productive. In an Dystopia, Customers simply weren't allowed to self-create things, to simply create things on their own. They would have to be made dependent from what Companies/Firms produce - and no-one else but them would have the RIGHT to actually produce things.
If I think it a little bit further into this Dystopia, then there would have been at one point in the past SO MUCH Lobbyism by Game manufacturers directed towards the State and the Lawmakers, that there's be a made a law at one point that no-one would be allowed to "produce" anything without a proper license.
Only Firms having an actual "license to produce" would not be punished for "Illegal Producing" - which would very much strengthen the companies who did all of the Lobbying (and much later of course got the very first Licenses) in the first place.
