We have seen many different techniques to effectively display compelling scenarios in real time. These game worlds are the perfect setting for our adventures. But who will the player be? Who will his enemies be? And his friends? In traditional drama theory, characters are used to make us feel emotions. We are attracted to or repulsed by them, and thus get attached to the story. ...
