Im not all the way through the article but it raises an interesting problem. To rephrase it: gold increases exponentially but the rewards and challenges do not.

Im not all the way through the article but it raises an interesting problem. To rephrase it: gold increases exponentially but the rewards and challenges do not. Gold gives you rewards, rewards are fun because they make challenges smaller, challenges require that you get more gold. It almost requires the game to change as you get stronger. Im not sure you can just make weapons/enemy strength exponential. That seems more like it needs to scale linearly otherwise you either gut utterly crushed or you utterly crush it and skill isnt involved.
