I think Game Pass is a great service at a great price and I think Microsoft's overall direction for gaming has been really positive and forward looking; however, I do worry about the consolidation of gaming. Activision Blizzard was fairly user hostile in their business practices, so I don't think this will be a net loss for consumers.
What I am starting to worry about is Microsoft squeezing Sony out of gaming entirely. For a lot of casual gamers Call of Duty was the game or one of a few games they play and have played for years. A lot of those casual gamers own a Playstation. While Microsoft hasn't announced if Call of Duty will be exclusive or not, making the game PC/XBOX exclusive would be doctrine. The only example I can think of where they don't do that is Minecraft, so it is possible.
I can’t imagine a scenario where Sony gets to have COD on their platforms in say… 2-3 years. Bethesda is also now only PC and Xbox. Microsoft is playing hardball because other than the fantastic deal that is Gamepass, they don’t really have a lot of hype building titles (Halo launched to a very mixed reception).
I personally prefer more companies rather than fewer. I also anticipate a large brain drain at Activision studios, like what has already happened at Blizzard. But the Activision brands are established enough (and formulaic enough) that it probably won’t matter either way.
