If you choose not to use the sample solution as a basis for your project, you must be sure to implement the important features of the sample code:

• You must be able to fly around the town to look at things.
• You must have "shortcuts" to go directly to places where particularly interesting things are.
• You must have several vehicles moving around. (this doesn't necessarily mean cars - one student had a space-town with ships flying around, another in a Harry Potter inspired project had brooms flying around castles)
• You must be able to control the time of day. The time of day should affect the lighting and the actions that occur.
• The program must be able to maintain a decent frame rate.

Writing things from scratch is a lot more work. We will give you some credit for doing it, but you will still need to do the technical challenges.
