1up.com: In Gravity Rush, you have one of the most ambitious open-world games ever attempted. No, it's nowhere near as big as a Grand Theft Auto or Elder Scrolls game, but what it lacks in scale it makes up for with freedom. The key concept around which Gravity Rush revolves is free movement in all three dimensions. Its name didn't come about by accident, after all. The protagonist, Kat, can slip free of gravity's proverbial surly bonds and flings herself in any direction.
