As the other user said With halo, Forza, gears, they were really hitting some home runs. Did this become a meme? yes but it was what the players wanted, so Microsoft should have just given them that but Don Mattrick wanted an xbox more like Playstation with narrative games this move was intended to make the platform attractive to Playstation players but it went wrong, it only served to alienate loyal customers while Playstation players remained on Playstation.
They should have just made Forza 5 (only) instead of wasting time and money with Quantum Break when Alan Wake had already been rejected for the Xbox 360 fanbase. Regardless of whether the specialized critics gave it a low rating, what dictates this market is whether the customer is buying the game or not. So even at the risk of becoming a meme, in my opinion you can't let anyone external decide how to manage your commercial strategy, only regular customers should be heard (they weren't).
The Xbox situation is very fascinating. because you don't fuck up so much a brand just doing only one thing wrong
in think the points that your are stating are not quite right.
1.
Give Xbox players what they want.
2. they tried to make "Playstation games".
i think we can agree that the Xbox identity was alway Mutiplayer games /co-op.
ok. is not like during the Xbox One era they didn't provide those games, in fact; the Horizon IP was a better evolution for the forza series and is a multiplayer centric game
but the the 343's Halo games got mixed reception from the fans.
and gears became stagnant.
in other words, they were making the games that "Xbox fans wanted" the issue is that their quality and luster was dropping (outside Horizon)
and then you could say... but they were trying to make play station games....
... I'm not sure they were trying to make play station games.
Xbox was trying the trans-media shit with quantum break; TV eisodes as part of its narrative. I don't think Sony has never made game like that
sunset overdrive was colorful and fun, stilized game closer to a jet set radio. Sony was doing serious over the shoulder realistic games.
crackdown 3 = Xbox legacy
sea of thieves = multiplayer .
ReCore = they were selling it like an inafune/metroid game
State of Decay = Base building, resource management.
Dead Rising = Xbox legacy.
phantom dust = Xbox legacy
Ryse = is the closer one to a sony game i think. but clearly didn't set the tone for what Xbox was trying achieve as a brand.
conclusion:
Xbox's bread and butter lost its luster and they failed at creating great genere defining games either Mutiplayer and Single player whatsoever.
