There’s no reason to “fully expect” this going forward, since the Xbox brand’s track record in this department has been abysmal for at least a decade. This would be like a Sony fan “fully expecting” the PS5 to focus on FPS’s, sports, and TV going forward, things that Xbox has hilariously been focusing on for a generation or more. The time to do what you are suggesting here, would have been at the start of last gen, going on the momentum and fanbase they had from the 360. Instead they totally squandered all opportunity to compete with Sony and Nintendo with exclusives, even with MS’s deep pockets and resources. How did they fuck that up? Clearly MS just didn’t care, which is why so many hardcore, traditional gamers hate them so much.
Yes, Xbox can turn things around, but they face a massive uphill battle, and there’s no reason to assume that Sony won’t be bringing the competition-crushing heavy hitters during this same time frame, like they always do. Plus, buying up a metric-ton of developers and franchises all at once is not how anyone else solves this problem, and is a very cheap and artificial way of doing it. Plus, even with Bethesda, etc, Sony will probably STILL have more exclusives. Plus, even with all of the new MS studios, Xbox STILL doesn’t have any exclusives, since everything is on PC. I mean, do Xbox fans even understand some of this stuff?
PS. The PS4 had multiple new, AAA IP’s. Most recently Ghost of Tsushima. Bloodborne. Dreams. Days Gone. Death Stranding. Horizon: Zero Dawn, etc. There’s more. Xbox has nothing of this caliber at this point. I’m sure more new IP’s are coming for PS5 this gen. But you’re right that this is a sore spot for many developers. This is more an issue with AAA third party publishers.
