When I was seven, I was given an Apple Macintosh in the hope that Mavis Beacon would teach me how to touch type. It was an unreasonable expectation, for I was actually more interested in escaping to the fantasy lands of Dungeons and Dragons and Lode Runner. Yet, these games had a lasting, unexpected impact on my thirst for learning. In playing Dungeons and Dragons, I remember being particularly excited each time my archetypal characters would gain ‘experience points’ that enabled them to upgrade their abilities.
