Microsoft was once in talks to bring Crytek on board as a first party studio, but eventually decided that Crytek projects of the time were too close in style and subject matter to certain Xbox 360 heavy-hitters.
That's according to Microsoft Game Studios vice president Phil Spencer, who told OXM at E3: "The first time we met with [Crytek CEO Cevat Yerli] and the team was around seven or eight years ago, and we started talking about what it'd mean for them to become first party.
"And it was a process of what do you guys want to do, what's unique for us, and they were just going to do Crysis, and they'd just come out of Far Cry, and we said we've probably got enough military future shooters, so go do that.
"Then they came up with this idea around Ryse, and now they've really fallen in love with Kinect, and it's a perfect marriage for us."
A first-person brawler, Ryse is the first action title to use Kinect as a full-body controller. Set in Roman times, it's worlds away from the slick near-future shenanigans of the recently released Crysis 2.
