Consider the following question:
How can I handle merging and splitting lots in a city block?
The original version of this question presents a reasonable problem that the asker would like a solution for. It is a well-defined, interesting problem relevant to game development, and would make a good question on this site.
Unfortunately, the asker then went on to present a pretty viable-sounding solution within the question itself and the actual question posed was "is this solution viable?" This reduces the question to a yes-or-no question, and perhaps related follow-up, but it generally does not make for a good question or good answers. We typically close this questions for a variety of reasons, usually because they are opinion-based or too broad (since we lack the relevant details and background to actually address the viability of the solution unless it's totally off the rails).
I would like to save these sorts of questions. So how should we go about that?
