There is nothing quite like Sleep Is Death. The idea is still as fresh as it was twelve years ago. When it came out, it was popular for a short while, but GMs were always in short supply. It took commitment to prepare the story, assets, and anticipate various choices player could make. Not many people went through the effort to learn the UI to create content in real time for players.

The currently ongoing Jason Rohrer's project "One hour one life" feels like evolution of this dynamic between player and the GM. The author is now a sole GM, he keeps track of community needs and wants. Every now and then the author creates new content (items, recipes, mechanics), which takes the in-game civilization a step further. The game is worth checking out, it has a quite innovative design.
