Despite Spelunky being a masterpiece (as close as you can get to a literally perfect videogame), I knew very little before reading this about it's creator Derek Yu. I expected him to be some John Carmack style uber-geek who dreams in C but he's anything but really - remarkably down to earth and relatable. It's fascinating learning from the horse's mouth how the game's features and systems came to be as part of Spelunky's rather long-winded development.

Maybe not one to read if you're not a Spelunky player, but if you know your eggplant from your Ankh then this is a must-read. ( )
