Kinect Sports Rivals will render at full 1080p, Rare executive producer Danny Isaac has confirmed to OXM.
Isaac said that the game began life at 720p, was bumped up to 960p and is now finally running at 1080p.
"We're at 1080p, but to be honest that was because our rendering guys just wanted to be at 1080p," said Isaac. "I think when you look at the platforms, now more than ever it's going to be about - OK, the graphics and resolution are part of the story, but there's also the service you have, the intuitiveness of the sharing, the multiplayer aspects of it."
It's no longer simply about which game is pushing the most polygons, says Isaac.
"I think that's still important, but it's much less of the story than it used to be."
Regarding the outcry over 720p Battlefield 4 and Call of Duty: Ghosts, Isaac said: "I think everybody always looks at numbers.
"If you think about photography and cameras, it's just megapixels, megapixels, megapixels. Can anyone really tell the difference between a 41 megapixel shot and a 21 megapixel shot? Probably not."
He believes the service a platform can offer is what's most important.
"So there's that part, but I think ultimately it's going to be the whole experience [that people think about], and I think while Microsoft's done well with the Xbox previously, what they've done with Xbox One is to build out that service.
"It's going to be about supporting that box as it goes through its life, delivering those services and experiences, outside of just playing the game. With things like Game DVR, where you can upload your clips to the cloud. Stuff that we could only dream of last generation is going to be a reality this generation. I think that's really where the battle will be, but obviously initially everybody just wants to compare the numbers."
That said resolution will continue to be the be all and end all for some.
"For some people that's going to be really really important. Some people will want to get high end PCs, and run at the highest settings they can, buy multi-thousand pound rigs to do that. But for myself personally, I'm more interested in the experience all around," Isaac concluded.
Xbox One launches November 22 alongside a trial version of Kinect Sports Rivals, named Kinect Sports Rivals Preseason. The full game will arrive in spring 2014.
