This double disc “Limited Edition” version of the first game of the infamous franchise is a nice item if you are a collector of the series. It comes in a standard Playstation box, with a different front and back cover and a change of livery for the game disc from the original release.
The main extra with this “Limited Edition” is the inclusion of a soundtrack CD featuring music from the game (i.e. the car radio). This is a decent little package and can be seen regularly on ebay. Prices should be in the region of £10, just make sure it is complete with both discs, manual and maps.
