I won Gravity Rush on a competition some time back and just started playing it as my first vita game and all I can say is that it's got huge amounts of charm. The main character in particular is so freaking cute
It's interesting that all the art on promo materials in the west don't seem to match up much to the actual art style of the game: it's much more Japanese in style than the cover hints at. I'm guessing they still think anime-style art doesn't draw in western players.
