Cliffski’s Blog has an article about "the long tail," offering one of those rare glimpses into the economics of independent game development, with a look at sales of Kudos: Rock Legend. In addition to the obvious figures breaking down the slightly over $50,000 the game has taken in, he also looks at the long tail of the sales figures: "But the good news is that long tail. Looky at the far right. The game continues to sell a few copies each month. If you have 10 games like that, then you are making a living (not an awesome one, but not a bread-and-water one either). KRL is not a whizz bang 3D game, so it doesn’t age quite as badly as most games will. I suspect in another years time it will still be earning 60-70% of what it does now."
