F rating.
Him and Aaron Greenberg have been a decade+ monumental failure for the Xbox business. They literally did so much damage to the business that they're now having to put Halo, Gears, Forza, and Fable on PlayStation.
J Allard and Robbie Bach, for as limited as their success was, had enough sense to know what Xbox was good at, what it sucked at, how to message the platform, how not to message the platform, etc. They never won a console generation, but at least they didn't Dreamcast the Xbox business.
Big papa Phil, on the other hand, was just a consistent stream of bad decision after bad decision and lies flowing into more lies. It's truly shocking that there are still a (small) amount of people who believe he was doing a great job as CEO. It would be like people believing an NBA coach is doing a wonderful job with a 5-70 record.
I wish him well in whatever he does next. But as Xbox CEO, he failed.
