He's taken Xbox back to a position of hardware power.
He's been at the helm for amazing consumer oriented programs like EA Access, Xbox Gamepass, Play Anywhere, 360 BC, and now OG Xbox BC.
If this E3 was any indication, he's brought indies/smaller titles back to the forefront, like they were at the end of the 360 lifespan, which was a great time to be a 360 owner.
I'm sure he wants to bring first party investment up, but it takes time. They had a strong first party showing at this E3, just nothing we didn't already know about aside from Forza 7. Also, PlayerUnknowns Battleground? Exclusive launch for Xbone? That's a big deal.
I think he's done a good job so far given what he inherited. Games take years to make. I'd love to see what his team brings for a new gen console launch.
