Rockstar Games' palm-sized Grand Theft Auto: Chinatown Wars was one of last year's best portable games. Scratch that. It was the best portable game of 2009-sorry, Legend of Zelda: Spirit Tracks. Whether you love or hate aggregate review score sites such as Metacritic.com, it's hard to argue with the numbers; GTA:CW pulled together scores of 93% and 90% for the DS and PSP, respectively. But despite the heaping critical praise, this latest romp through Liberty City failed to post the kind of sales numbers the blockbuster series was accustomed to. However, like a low level street thug determined to climb the criminal underworld ladder, Chinatown Wars isn't about to give up. With the DS and PSP debuts a distant memory, this ballsy entry now has its sights set on Apple's iPhone and iPod Touch.
