Gravity Rush is a fusion of Portal, a 3rd person adventure game; with strong RPG elements and collectibles, it's quite ambitious and I felt they pulled it off nicely.
I've never played a game that controlled like this, at times it was frustrating but most of the time it felt good; this game really takes advantage of all the unique features of the Vita without throwing them in your face, everything just felt right and natural.
Story was a bit too anime in parts but overall decent, more than I was expecting, a lot more. The game was also longer than I expected I think I probably put 12-15 hours into it, I did most of the side missions, but there are still many collectibles I didn't get to and challenge missions I didn't complete.
Great graphical style, this game really shows off the power of the Vita.
I'd say it's worth getting a Vita just to experience this game, it really blew me away, probably my 2013 - 2012 game of the year.
