Firstly, I personally believe this is not a duplicate of Question with Vague title as this question is a lot more specific while that one covered a broad number of points and was thus difficult to answer, I also find it difficult to understand due to the mix of stating opinion, stating fact and asking a question, the answers were also resultantly vague, I wish to ask a much simpler question purely regarding community consensus and policy.
An example:
I just noticed from this question that a VP and moderator edited a question solely to add the name of the game (which was already in a tag) into the question title.
The question:
Should question titles contain the name of the game and if they do/don't is it valid to edit them purely to change this?
