There's absolutely no way you can argue that Mirror's Edge is a bad looking game on a technical level unless you're prepared to argue that more recent games like every Mass Effect and Gears of War title look like crap too. They all use the exact same engine.

Along with all of the Arkham games, Dishonored, and pretty much every other game released this generation.

And put in a disc? I play this on PC son. The way it's meant to be done.
