There is no shortage of pre-built objects, such as lights and cameras, in Unity. Some of these are vital to any game. Stock geometrical objects in Unity, such as planes, cubes, and spheres, are good for establishing basic shapes.
You've also learned all the programming fundamentals you'll need to make a game. It may seem like the code you wrote was small—and there is still plenty to learn—but knowing the anatomy of code as well as how to take advantage of every line and function keyword is the hardest part of programming; the fun lies in transforming your imagination into code.
In the next chapter, you'll continue working with scripts and write code that enables you to interact with the game objects in your scene using your keyboard...
