A very clever way to go out.<p>It instantly reminded me of the story of when Carmack and Romero decided to go on their own after they were working together at Softdisk. At the time, there were no side-scroller games for PC for performance reasons. Carmack (20 years old at the time) had an idea, I believe it was about shifting the pointer of the display (or something to that effect), that allowed smooth side-scrolling enough to emulate the effects of the NES. He stayed up all night, and left a floppy at Romero's desk for the next day. When Romero got in the next day, and played the disk, Romero pretty much said "That's it, we're outta here" and from that initial engine was born Commander Keen, and the beginning of the legend of John Carmack.<p>It's been a few years since I read the book "Masters of Doom", so some of the details are hazy, but I thoroughly recommend it.<p>Carmack's genius is just out of this world.<p>Edit: Factual Correction.
