@BerndWill:
(from memory) GPGs I is a very good introduction to techniques from a wide variety of game genres. GPGs II and onwards seemed to specialise on specific aspects of these - much more depth but less eclectic than the first one.
Amazon often do bundles and Charles River offer a package of the first three - both good ways to save on multiple volumes... but I would recommend that you get hold of Vol I to see whether the style suits you...
