My guest on today's show is David Farrell, lecturer in videogame design at Glasgow Caledonian University. We recorded this live at the university and discuss the amazing set up that they have and the fun toys they can use to understand how people play games. There is some serious 'What is a game?' chat so be prepared, and we delve into David's videogame history, from tape trading on the spectrum to time management in The Witcher 3. David also talks about his job, and how teaching games and teasing apart how they work can be just as much fun as playing them.
