First, be aware that you need to contact the author directly via email for the resource files to these projects. The book itself is nothing but screenshots of the games - no text, no explanations, nothing.The projects themselves are barely games - mostly buggy prototypes that show some gameplay elements from each of the game they emulate. However, none of them are finished, so you won't get any understanding of how to handle things like:Multiple levelsControlling enemy spawning/predefined wavesDecent physics setupsSaving/Loading gamesMultiplayeretcAll of which are things you'd expect to see if any of these projects resembled the finished games they emulate.Save your money for better examples of how to use GameMaker, you won't find anything of value here.
