I love tutorials. That is one reason I buy so many books. The Game Programming Gems series of books (and their siblings the AI Programming Wisdom books) and essentially thick hard-cover books chock full of tutorials with some related code on the CD. I have volumes 2-5 of the Gems book and both volumes of the AI books and they are the best game programming books that I have bought. I have not even looked at all the CDs yet, but I have read at least a bit of each and every article in each book.
