I asked about non-D&D megadungeons and I was looking for either a "No" or a comprehensive answer. What I'm getting are single bits of what could be a comprehensive answer, spread across multiple answers.
At what point should a question be turned into a community wiki? Should these sorts of questions—ones that could have a comprehensive answer, but just aren't attracting one—be turned into a CW earlier, or should the asker and the community hold out for a comprehensive answer? Generally, should we be pro-active about converting to community wiki, or patient about it?
