Trapped in the world of gaming since the days of Asteroids (and never quite getting what all the fuss about Pac-Man was when there were games like Tempest and Robotron to be played), James has been playing games long enough that he should know he'll never be really, really good at them.
Unlike a fair percentage of gamers, James doesn't have a dungeon but rather a loft - which is much like a dungeon but with better views. If he could be persuaded to stop looking at the TV screen or computer monitor for a few minutes, he might even notice them.
