If Gameloft's Gangstar: City of Saints on iPhone is guilty of being too straight-laced in its attempt to depict gang culture, its sister title on mobile is guilty of the opposite.
Where City of Saints felt rigid and positively lifeless on touchscreens, here the streets feel far more jumbled and hectic. Java's version of Rio is far more alive, despite the inevitable graphical sacrifices.
It's not generally fair to compare Java games with iOS games, but in this case it's worth lining the two titles up in because they're so utterly different.
