With a score of 9.5/10, Chinatown Wars on PSP is officially Gamespot's highest rated PSP game of all time.

"At first glance, Chinatown Wars could be mistaken for a return to the Grand Theft Auto series' humble 2D beginnings. The action is viewed from a more or less top-down perspective, and of course you still spend much of your time driving stolen cars and causing trouble with firearms. But the similarities between this superb PSP game and its '90s progenitors pretty much end there. Chinatown Wars actually has more in common with GTAs III and IV than it does with earlier games, and, remarkably, it even adds to and improves on the formula that made those games so successful. That's a bold statement for sure, but Chinatown Wars really is that good... It's also one of the best GTA games yet."

The critical response thus far?

A perfect 10/10 from Play Magazine, which called the game "The new best hand-held title of the year."

Another 10/10 from Videogamer.com: "The game boasts some of the most inventive missions in GTA's history...GTA: Chinatown Wars is my favourite handheld game of all time."

Eurogamer deliver a 9/10 and highlight the upgrades made in the transition to PSP: "Not only are the textures much higher-resolution throughout the world, but the once-squashed comic cells used for the text-based story sequences look beautiful spread across the PSP screen."

Gamepro's 4.5/5 comes with a glowing recommendation: "Chinatown Wars remains an absolute blast from start to finish with plenty of trademark Liberty City locales ripe for exploration... If you're looking for a good action adventure experience that harkens back to the more cartoony Grand Theft Auto days, then Chinatown Wars is certainly worth the investment."

Now Gamer scored the game a 9.5/10, stating "GTA: Chinatown Wars on PSP is bigger, looks better and arguably offers the definitive handheld GTA experience. If you’re a fan of the series, you won’t want to miss it...Grand Theft Auto: Chinatown Wars has perfectly translated to the PSP and is a must-have game."
