Jigsaw member Curtis Himel continues his popular class on game development with Unity, an increasingly-popular game engine used by both indies and large studios. With the engine integrated directly into the development environment, Unity is (relatively) easy to use and allow real-time changes to your game with immediate results. Making a quick game is probably easier than you think! (And probably cheaper too since Unity has a highly-functional free version.) And once your game's done, you won't have to do it again since Unity publishes to nearly every platform available from mobile to Windows to X-Box.
Before the class, you should download and install the free version of Unity game engine 4.2 from http://unity3d.com/unity/download . Also, a mouse with scroll wheel is somewhere between useful and required.
