Heh, I mentioned once before that my cousin's husband wrote the Prima guide for SRTT. He gave me a free copy and it's "ok" for what it is and the various charts for cars (speed, handling, etc) held my attention for a few moments but overall it's nothing anyone would need. The only information in there you might not find just in the course of playing the game would be the location of all the cash/sex doll goodie packets.
Aside from that, there's only so many ways you can say "Enter the room and guys will try and shoot you. So shoot them."
