File under "D" for "Duh".
Anyone who has been a multiplatform gamer for the last decade knows this is the case.
Xbox forgot that it was the games that mattered before the end of the X360 era when they started trend chasing with Kinect. That was the beginning of their ten year long slide. Kinect, then the blunder Xbox One reveal, a streak of middling Halo games, and Gears games that, while not bad, simply weren't anything groundbreaking compared to their predecessors. Bungled game launches like Sea of Thieves that took literal years to finally establish itself as a decent new property. Forza Motorsport and Forza Horizon have been doing a lot of work to keep the Xbox brand afloat. Without the Zenimax acquisition, they'd have nothing this year except Motorsport.
The only people who argue otherwise are single console, Xbox-only fanboys who have been bamboozled by a decade of PR spin telling them that "THIS year will be THE year of Xbox", only for the year to come and go with little to nothing to show for it. They've been brainwashed into believing Sony and Nintendo are the root of all their problems and act like a persecuted religious minority when the real problem has been, and always will be, located in Redmond, Washington.
