So my november entry in OneGameAMonth is Grey Plains. It's basically a randomly-generated series of encounters. Each encounter is solved using a specific item, like many old adventure games. You go to encounter A, get item X, use X to solve encounter B and get item Y, etc.
The game was an experiment in generating a plausible-well, mostly plausible-series of encounters linked together in a logical way. Of course there are no flamespitting hamsters or vending machines out in the barren grey wastelands so it's not perfect. Given more time I would have liked to generate a larger pool of encounters to draw from as well as fleshing out each encounter a little more.
