A Little Baring of the Soul
My greatest personal motivation for putting emotion into the games I design and write isn't any of these nine reasons. I add emotion because, as an artist, it's what I do.
When we think of ancient Greece, we remember its temples, its statues, its plays, literature, and mythology. We think of its art.
So, though the primary reason for putting emotion in games might be to make money, that's not what fuels my greatest passion, nor the passion of many other game designers I know. The fuel is the desire to create entertainment and art.
If we can get used to tiny Dutch windmills taking up residence on small golf courses upholstered with green indoor-outdoor carpeting, then we should be able to survive money interwoven with art. When a breadth and depth of emotion is added to games, then profits are increased and art is enhanced.
