If there's one game exclusive to the Xbox One that looks great, it has to be Quantum Break, from the developers of Alan Wake and Max Payne. Quantum Break is a game all about time-amplified gameplay, where you can manipulate time itself, as time within the game is breaking.
Sam Lake, Remedy Entertainment's Creative Director (and the face of Max Payne) walks us through the 16-minute gameplay video, showing off an incredible amount of the game. Time stutters are shown off, frozen moments that shift and collapse without warning, or timelines in loops are crashing into each other. All-in-all, it's an impressive look at the Xbox One exclusive, something that is sure to sell well.
For an Xbox One game, it looks great - but no details are known as rendering resolution and frame rate. If I had to guess, it looks like 900p at 30FPS, but I'm sure we'll hear more on that in the near future. As for the gameplay, it looks great, but I with there were more lasting environmental effects, and more use of the environment itself. It feels static, with playability probably not that high.
