The subjectivity spiral seems a little redundant here. Clearly, the market doesn't think whatever Xbox is putting out is worth buying the console, buying the games, or even subscribing for access to them.
You're right, so let's look at that.
Even in the last segment of Don Mattrick's regime, you could see the cracks starting to form as Xbox tried positioning itself to be a multimedia, always online ecosystem. It's not that far removed from what Gamepass is. The Gamepass/Play Anywhere/multiplatform release model is just the logical conclusion, all the way from deprioritising the dedicated hardware to universal access; just with subscription economics slapped on top.
Not to be rude, but I'm not even going to debate the promise or quality of Redfall, Starfield, or even the latest Forza that they managed to bungle, because lol.
As for this year, I truly think their lineup looks less up to standard than it ever has since Crackdown 3.
Hellblade's gameplay looks as scripted and inelegantly designed as the first game's, and after 7 years of no new releases, Ninja Theory has only been able to crank out 8-10 hours. Nobody expected that after 3 years of hype from Xbox marketing. Indiana Jones just looks bad. Avowed looks like a kickstarter campaign project and sounds so tired. Every bs promise these RPGs come out with is regurgitated in that deep dive.
If not for quality, it's objective to say that production values appear to be lesser, or way less efficient.
