(I say all this as someone enamoured with the first console as it was a core moment of my upbringing)
It was xbox yesterday, it's Windows today. Microsoft is on the way out.
The original console cost a billion dollars to produce(confirmed in the documentary here: https://youtu.be/yT_i6hXf9WU?list=PL0il2l-B_WwadxfTkK3-NLoYN... ).
There are xbox engineers confirmed reading these forums so maybe some of them can shed some light but it seemed like the first console was a dud for multiple reasons and they killed it off early. Why would they do that if it was making money?
The second console was on its way to being a blockbuster until the RROD issue cost them at least a confirmed billion dollars in losses(also mentioned in the documentary here: https://youtu.be/z2d6IMBS8oY?list=PL0il2l-B_WwadxfTkK3-NLoYN... ).
So thats a confirmed negative two billion dollars and we haven't even talked about the cost to develop 360.
Sony caught up to them after RROD and managed to turn PS3 around so 360 didn't even end the cycle as number one in sales. After that, they never had any real success again and continued to fall further behind until today.
Continue to provide value and win over customers?
Both Playstation and Nintendo Switch significantly exceeded xbox in terms of good games in the last decade imo.
But the Xbox hardware is good, franchises like Halo / Gears / Forza etc. have always been good, and Xbox Game Pass is great.
The problem was the lack of hit IPs, and buying a bunch of studios with good histories like Bethesda was on the surface, a logical choice. The problem is that the Western AAA industry was also undergoing through a general decline amidst a larger cultural shift that was anathemic to originality, so no new hits could be made.
Nintendo and Sony in contrast still had a portfolio of more niche legacy studios like Monolith or Atlus or Kojima that could create new things. Obviously the talent for that does exist in the West, from Larian or smaller indie studios, but it is very hard for upper management to discern these kinds of details or be willing to take the risk with them.
