In this chapter I have discussed just a few of the elements of good gameplay: unique solutions, non- linearity , modeling reality, teaching players, and input/output. I feel that each of these components deserves serious thought as you set out to develop a game. Of course, this is far from a complete list, and as you work as a game designer you will accumulate your own personal list of elements that you feel contribute to good gameplay. No one can say for certain what the elements of good game design are. Each game designer must decide that for herself. This personal preference is part of what makes each game bear the distinct stamp of its author and lends the best games the individuality that makes them great.
