Manu's Finding Haven began as a contest entry and runner-up in the 2013 Iron Game Chef, and the accompanying tale is familiar to me. Briefly, these contests degenerated quickly into a takeover process in which game designs disintegrated. I have a fairly reliable procedure in my pocket for this situation. The underlying logic goes something like this.
A person began with X or rather "X," a notion or hope regarding some topic and/or way to play it. In handing it over to others' review and participation, "X" disappeared to be replaced by a kind of stew of claims and suggestions. That led to changes to please those persons but which were then encountered by others, which only led to more claims and suggestions. So now the person is looking at a sheaf of procedures which purport to be "baked by playtesting" but which are really more like a kitchen that was overrun by several waves of fratboys, all of whom snacked, none of whom paid attention to what the kitchen might have been initially set up to do, and each of whom left a particularly individualized and disturbing wad of detritus scattered after them..
My job at this point is simply to reconnect with the initial "X." I'm not necessarily stating that it will be exactly what the person wants or needs now, but there was most likely some kind of inspiration at work there at least to describe and remember. Better to work from there instead of roaming around the kitchen mess pretending that it is a recipe in progress. Maybe "X" is beautifully set up to become a real X, or maybe it's a good springboard for realizing that one would like to begin again with "Y." And, worst-case scenario, if there wasn't an authentic inspiration, e.g., if the whole thing was a moment of pastiche or vanity which has bobbed along on fumes ever since, then we might as well know that now, pop that bubble with a pin, and be done with it.
Sometimes a person is a bit surprised to discover that "X" is still there, having been told so many times what to change and having been blinded by all this alleged fun the fratboys had in the kitchen doing what they do there.
