A number of gaming sites have tonight posted their own hand-on previews of the PSP version of Chinatown Wars. In addition to the previews there are also some brand new screenshots of the game. At the end of this post is a list of sites you can read previews of the game on. So go ahead and pick your favourite for all the juicy details.
A quote from IGN:
... there's a whole bunch of bells and whistles for the PSP audience. The graphics have been overhauled so that there's bloom lighting, slicker cars, and proper use of the system's wide screen; there are six more radio stations that pack an extra 100 minutes of tunes; and there are new rampages, riding shotgun missions and more.
