[2Ed] Chapter 08: Design Goals
This chapter explores several important goals that you may have for your games. It covers everything from the deceptively complex goal of fun to the goal of experiential understanding, which may be unique to interactive experiences.
As you read this chapter, think about which of these goals matter to you. The relative importance of these goals to each other will shift as you move from project to project and will often even shift as you move through the various phases of development, but you should always be aware of all of them, and even if one is not important to you, that should be due to deliberate choice rather than unintentional omission.
