As a reference template to help you better understand the practical operations explained throughout this book, we plan to create a game prototype, featuring 2D gameplay with 3D graphics.

We believe this solution nicely fits two distinct needs: on one side, 2D gameplay is lighter to prototype, allowing us to describe the many features of Unity without the burdens of 3D mathematics.

On the other side, using 3D graphics (specifically for the game character and other game objects), we have the opportunity to discuss very important Appendix features of Unity, which would go unnoticed elsewhere. In the end, Unity is an engine to make 3D games, mainly!
