I recently wrote a short article on feedback loops and game design for Hyperbole! Games. If you're interested take a look and feel free to comment: http://hyperbolegames.com/2012/05/11/game-design-gone-loopy/
The music analogy clicked for me, and I thought of a couple solutions to my runaway leader problem. All this time, I just had to ask myself What Would Jimi Do?
Fantastic article, and really well written. Nice work drktron!
