OK, I have to say, while I liked the PotC3 VG book, it's pretty much a collection of photos of props and costumes. There are some cool features, but I'm the mom of a 5-year-old, so we're easily entertained. I also like to see the detail in the costumes. So, I'm not sure the VG is for you.
Now, on the other hand, I just got a good look through The Art of PotC. THAT book is amazing. The whole thing is the concept art, from the first movie, where they didn't have the actors pinned down, to the last, with some AMAZING detail sketches. It's absolutely gorgeous, and I've let me captain know that one goes on me Christmas list.
