What the hell is a Type Object
First of all this book is targeted for budding game devs.
Second, with a double layer DVD the challenge is made to be filling it with game. But it doesn't have to be.
Third, this chapter only works for ideal projects that are simple and when the game has been formally specified.
Based on this chapter and the above 3 points, you need to level up. Don't just blindly jump into game dev, it will consume you like a bundle of dry twigs.
Goodbye! Cruel Hello World! Wait, I need to create a Design Pattern for that ...
