Sidetracked By The Golden Saucer: In usual Grand Theft Auto tradition, the amount of secondary play elements (drug trading, taxi driving, ambulance rescue, rampages, scratch cards, etc.) make it all too easy to spend hours of time in Chinatown Wars while barely touching the main story.
Polished Port: The PSP version got graphical improvements, several new radio stations and an entire new series of missions for reporter Melanie Mallard.
Visual Effects of Awesome: Chinatown Wars looks quite impressive for a DS title. Aside from the fact that the entire map of GTAIV (well, minus Alderney) was squeezed into a 512MB cartridge is reason enough for applause, but the game one-ups that by delivering an impressive level of detail, realistic vehicle physics (vans are top-heavy and wide-turning, sports cars turn on a dime but are ridiculously fast, etc.) with flippable cars, bright vivid colors, and all under a consistent 30FPS. The PSP and iOS editions are even better, with richer color schemes and highly detailed lighting and effects.
Overshadowed by Controversy: Some people only remember this game for the drug dealing mini game, and the fact that it was released on a Nintendo console initially.
