Drawing A Scene

I learned that there is a lot more to making a game than I thought and a lot more work. How did you come to learn this? I came to learn this about halfway through our paper prototype it took a lot of pages.  What sources where helpful to you in gaining this understanding? The wiki helped me by explaining it even though I liked the hands on more.  What makes these news or research sources especially informative and trustworthy? That they come from the makers of globaloria and other game makers.
