All the games mentioned have single player parts that feel like an after thought compared to the online portion.
Which is why they seem to be doubling down more on online games, and game services. Is because their first party single player focused games haven't done well. Ori, Ryse are the only ones I can think of that sold really well.
They are making these changes because of the parent company's outlook for services, and because their first party efforts for single player campaign type games have fell pretty flat.
Feel like afterthoughts? So you've played these games then?

The only game that is any different from what MS has BEEN doing is Sea of Theives. Everything else is inline with industry trends THAT EVERY OTHER PUBLISHER IS DOING- adding MP to SP games, making some online only games, and adding MTs.
Every conceivable business model is represented in their portfolio.
MS been doubling down on online games since 2002.
