I worked on a Ph.D. for a number of years, mostly on the side of other, design and development related jobs. The work was finally completed in late 2007, and I defended the thesis in March 2008. You can download a PDF from the link below, or head to Amazon to buy the book.
In the thesis, I construct a theory of what elements games are made of, and complement the formal, structural approach by applying studies and concepts from psychology in order to understand the experiential and emotional experince of playing games. The theories lead to a number of analysis methods and design implications, which I try to illustrate with a number of case studies. The ‘100+ Games Project’ is a part of the thesis, where I have analysed more than 100 games – across different media ranging from pen & paper to computers – with the methods.
