I was looking for the most important metric in the article - how many jobs have you filled so far? I have limited bandwidth for free-time coding, and anything has to compete with my own side projects and "list of things I need to learn/revise to keep head above water in notoriously mercurial industry". If I were to invest time in Starfighter, I'd need to know that, assuming I do my part and finish the game with a reasonable score, that a) it will land me an interview and b) it will do sufficient pre-vetting of my skills so that the interviewer doesn't need to throw whiteboard curveballs. If I saw some kind of metric on job placement I might think it's worth spending time on. Otherwise my time would be better invested in improving my Github profile and resume and building my network.
