It is true that question rate is an important criterion for graduation but there are 13 sites with a lower question rate than us. That includes some that have been in beta for four and a half years. I'm not dispirited.
For one thing, spread the word that we are here. We need a bit more visibility. I've seen questions get closed ...
There are a number of sites within the SE network that have identify-this tags, so why not this one?
Note that a few of these sites periodically have on their metas a proposal to ban them. Particularly where there are a lot of such questions. See the soul searching on Movies & TV, a site that has a large number of them.
As with all questions, they ...
Title case makes things stand out
Title case should be used when you're trying to make something stand out and grab people's attention, such as in a bold newspaper headline. As we've already got formatting to distinguish the titles from the content (bigness, position at the top of the page) we don't need to put them in title case to make them stand out.
Wizzwizz4's answer already brings the main point home: Ideally, yes
Having tried myself to improve less than optimal titles, I had to learn that it's not as easy as assumed. A titel should be a question, but it needs as well to give a rough hint on the backgound. Forming it as a question may come second.
The most importent part of a title is being a title
When titles are questions, they're more likely to actually describe the post. Looking at the related pane of this very question will demonstrate that.
However, there are cases in which it is difficult to summarise the post into a single question, even if the question is narrow enough for a single answer. As such, it might be acceptable to ...
No, the question summary should not be written as a title.
I've struggled with this myself in the past and not come to a satisfactory conclusion until now. wizzwizz4's answer gave me some further insight and makes a lot of good points, but it doesn't mention what I now believe to be the chief point: how this field is used, i.e., who is reading it and why.
I don't care
My bias is much more to content quality than typography (It may be different in Tex/Latex). If someone wants to post a question using all uppercase (or whatever case he likes most), I'm fine, as long as it is a useful and interesting question.
Let people use whatever case they like most.
I don't think retrocomputing is appropriate for these types of questions. Gaming.SE might be a better fit for these types of questions, as they are dedicated to gaming across multiple generations.
If we allow game identification questions, this site might become a dumping ground with them, rather than general retrocomputing questions.
There is a long-standing question on this on the main meta - Should "questions" be questions?
The consensus is "usually yes".
It is possible to construct a coherent question title that is not, in itself, an interrogative. However, for clarity and for ease of finding in searches, a question title is usually best when posed as a question.
If an edit to the question changes the question's scope, it has to have a pretty good reason. Otherwise it will be reverted. An answerer is allowed to do this, but they must have a good enough reason.
I'm not sure of the reason for the change in your example.
I think "identify-this" should be permitted, subject to the same restriction as on Gaming.SE: you need to have some artifact from the software. This could be
A clip of the soundtrack or a distinctive sound effect
A photo of a pair of peril-sensitive sunglasses
A distinctive line of text ("YOU ARE IN A MAZE OF TWISTY LITTLE PASSAGES, ALL ALIKE."...
