Just because the Xbox One is front and center right now for Microsoft, that does not mean PC has been forgotten. Speaking with Shacknews, corporate vice president Phil Spencer admitted Microsoft has not given enough attention to PC, but said this won't be the case going forward.

"I think it's fair to say that we've lost our way a bit in supporting Windows games," Spencer said. "But we're back. You'll see us doing more stuff on Windows. We probably have more individual projects on Windows than we've had in ten years at Microsoft Studios."

The games Microsoft has in the pipeline for PC are not casual or "lightweight" games, but rather titles aimed at core gamers, Spencer said.

"At the launch of Windows 8, we had about 30 games in the Windows Store. A lot of those you'd consider lightweight or casual games," he said. "But we've covered all of that property now. Now we're starting to look at bigger and core gamer things. I'm excited by that."

Overall, Spencer explained that gaming efforts on Windows have become "incredibly important" for Microsoft since outgoing CEO Steve Ballmer introduced the "One Microsoft" plan in July.

Notable upcoming Xbox One games also coming to PC include Project Spark and Titanfall.
