i bought this book and its really good on getting you to understand alot of the basics around game programming in dbp.
it handles all the aspects of game making with dbp but is in one single book so some stuff are really little written about.
both 2d and 3d games and multiplayer games.
iam still waiting for hands on dbopro vol 1-2 havent got them yet.
i learned alot of stuff in the core commands in dbp in this book.
