As you might imagine, making things difficult is a tricky business. If a game isn't difficult enough, experienced players lose interest. On the other hand, if it is too difficult, the initial enjoyment gives way to frustration. In fact, several psychological factors hang in a delicate balance: challenge, enjoyment, frustration, and curiosity. As the stu- dents reported, "Once the curiosity is lost and the frustration level becomes too high, it is hard to get a person's interest to return to the game." All this has to be considered, yet the game must maintain its appeal for players of many different levels, from first-time players to experienced players. One approach is to sprinkle the game with many different challenges of variable difficulty. Another is to have many little things continually happening, maintaining the curiosity motive. The same rules that apply to make tasks understandable and usable also apply to make them more difficult and challenging; they can be applied perversely to show where the difficulty should be added. But difficulty and challenge should not be confused with frustration and error. The rules must be applied intelligently, for ease of use or dif- ficulty of use.
