Slowly raise the bar . Now that players are flush with victory and craving more, it s time to up the challenge. If every race is as easy as the previous one, there s no sense of accomplishment and no motivation to improve, Della Rocca says. As players hone old skills, they gradually learn new ones. Steering around the figure 8 race track on the fourth level is trickier than maneuvering the single loop on level one.
Obstacles appear, requiring the player to learn a new skill, handling the clutch.
As the skill level increases, so does the intensity or duration of effort required to master it, adds Della Rocca. I have to concentrate more. I have to be more precise with my steering. A standard element of game design is to unlock new features and add more options as the game progresses, he says. That s part of the enticement.
