In fact, the games I tend to make progress on are the ones I can get testable as quickly as possible. Unfortunately, those are usually the least complicated ones (glorified MUDs, an x axis with only 4 possible positions, etc).

I do want to do bigger and better things, then I run into the same problem as CronoDAS. When I do start a bigger project, I can sometimes get started, then crash within the first hour and never return. (In a couple extreme cases, I lasted for a good week before it died, though one of these was for external reasons). Getting started is usually the hardest part, followed by surviving until there's something work looking back at. (A functioning menu system does not count.)

This seems like a really good concept to keep in mind. I wonder if it could be applied to other fields? Could you make a pot that remains a pot the whole way through, even as you refine it and add detail? Could you write a song that starts off very simple but still pretty, and then gradually layer on the complexity?

Your post inspired me to try this with writing, so thank you. :) We could start with a one-sentence story: "Once upon a time, two lovers overcame vicious prejudice to be together."

And that could be expanded into a one-paragraph story: "Chanon had known all her life that the blue-haired Northerners were hated enemies, never to be trusted, that she had to keep her red-haired Southern bloodline pure or the world would be overrun by the blue barbarians. But everything was thrown in her face when she met Jasper - his hair was blue, but he was a true crimson-heart, as the saying went. She tried to find every excuse to hate him, but time and time again Jasper showed himself to be a man of honor and integrity, and when he rescued her from those lowlife highway robbers - how could she not fall in love? Her father hated it of course, but even she was shocked at how easily he disowned her, how casually he threw away the bonds of family for the chains of prejudice. She wasn't happy now, homeless and adrift, but she knew that she could never be happy again in the land she had once called home. Chanon and Jasper set out to unknown lands in the East, where hopefully they could find some acceptance and love for their purple family."

This could be turned into a one page story, and then a five page story, and so on, never losing the essence of the message. Iterative storytelling might be kind of fun for people who are trying to get into writing something long but don't know if they can stick it out for months or years.

I submit that this might generalize: that perhaps it's worth, where possible, trying to plan your projects with an iterative structure, so that feedback and reward appear gradually throughout the project, rather than in an all-or-nothing fashion at the very end. Tight feedback loops are a great thing in life. Granted, this is of no use for, for example, taking a degree.
