I made a google form once to help me understand what my players were excited about. It only came up because I hadn't got anything in particular in mind to run, and wanted a way to help them articulate what they actually wanted (can be a challenge). I found the results illuminating, and the resulting campaign was probably my most sterling success (and is still running). I wonder if anybody else has tried this or something like it?
