Dijital Oyun Rehberi is a new book we just completed, soon to be in stores. I am one of the editors and Başar is the cover designer. The subjects are: Traditional games, simulation, game design, value chain, productive contribution of gamers, modding and machinima, Turkish gamers, game expertise, MUDs, real life simulations, MMOs, game studies. If you are interested to buy & read, I can help.
By the way, you can follow my GDC notes from Dijital Oyun Kültürü blog.
