Mirror's Edge originally looked like "every other Unreal game" in 2008, but it literally made people sick: "Moving very fast through the world, you got simulation sickness"

In the nearly 18 years since its release, Mirror's Edge has built a sparkling reputation for its sparkling buildings and blue skies. This, apparently, wasn't developer DICE's plan.

The parkour game's developers reflect on its now incomparable look and feel in a new interview with Design Room, where they admit Mirror's Edge was originally set to join its apocalyptic siblings – like Gears of War or Fallout 3 – in looking very, let's say, piss yellow. But looking at this corroded version of Mirror's Edge literally made people nauseous.

Senior producer Owen O'Brien explains that "Mirror's Edge started off looking like every other Unreal game, to be honest." But here's where listening to your body is important. O'Brien says, "we found that when you were moving very fast through the world, you got simulation sickness very quickly.

Mirror's Edge looked "pretty brown, like a regular game, if you will," he says, which "wasn't bad; it looked good, actually. But there was no style to it, or a fairly generic style."
