You may have noticed that Microsoft's E3 press event was heavy on the Xbox and rather light on Windows—which is to say, it didn't come up at all. According to Phil Spencer, the head of Microsoft's Xbox division and Microsoft Game Studios, there's a good reason for that: E3 is a "console show," and Microsoft didn't want to bring a gun to a knife fight.

Speaking to Polygon , Spencer said it's arguable that Windows gaming is in better shape than ever thanks to big franchises like League of Legends and World of tanks, which "dwarf a lot of what we're doing in this console space in terms of users and monetization." But bigger isn't always necessary better, and because E3 is so heavily retail-focused, "it didn't really like the right place for us to talk about Windows."

"For us, E3 is a console show and an Xbox show, and for us as Microsoft, Xbox is our gaming brand, and it's the thing we can fill an arena like this, we get millions of people to watch us on TV and we show our games and it's a brand that people care about," he said.

I'd just assumed that Microsoft was continuing its usual enthusiastic support of the PC gaming space (and for the record, Spencer described Windows gaming as "critical to Microsoft's success") by ignoring it completely, but I guess this makes sense too. And it's not as though Microsoft doesn't have a PC plan: Spencer noted that "they do these huge world championship events and they fill up arenas," and that it could probably do something with that.
