The other journal article by Panagiotis Migkotzidis and Antonios Liapis "SuSketch: Surrogate Models of Gameplay as a Design Assistant," develops the M.Sc. dissertation of Panagiotis where he has developed an AI game design assistant. It leverages machine learning to provide the designer with predictions of the gameplay for two competing players of specific classes.
The interface allows the designer to work side-by-side with an artificially intelligent creator and to receive varied types of feedback such as path information, predicted balance between players in a complete playthrough, or a predicted heatmap of the locations of player deaths.
A demo of Panagiotis's tool can be watched here:
