In general, I'm in agreement that a question which:
- Asks about a game thing
- Points to the thing in a concrete manner
- Asks what that thing is
is not off-topic simpliciter, but I want to point out that they do not automatically make a question on-topic either.
You've linked to three questions that have been closed:
- What is the Font Used in Pokemon Conquest?
- http://gaming.stackexchange.com/questions/73330/what-is-the-font-used-in-heroes-of-might-and-magic-3
- http://gaming.stackexchange.com/questions/39631/christmas-song-in-the-polynomial-steamworks
These questions you listed were, in my estimation, correctly closed even if they had only a passing resemblance to identify-this-game questions (see below for why I think that.
That's not to say that there are some questions that roughly fit the category of questions you're talking about; here are just a few examples (all open):
- Who wrote this incredible theme-song?
- What is the origin of the Qin Shi Huang theme music in Civilization IV?
- Who performed the works of John Adams for the Civilization 4 soundtrack?
So, after discussing it with you and others over the past day or so, this is more a problem of people leaving comments that mischaracterize the nature of a close (i.e., pinning the blame on a passing resemblance to an ITG question), and it's something we should fix in general.
Inside baseball and sausage making regarding why I think the questions you linked to should be closed anyway follows.
The font identification questions
- What is the Font Used in Pokemon Conquest?
- http://gaming.stackexchange.com/questions/73330/what-is-the-font-used-in-heroes-of-might-and-magic-3
These two are font identification questions and were correctly closed as off-topic. It's not because they bear a superficial resemblance to identify-this-game, but because they are fundamentally not gaming enthusiast problems.
First, there's knowledge required to answer: either inside knowledge of the game or an expertise in typography.
The former is the primary reason why "why did they design it this way?" questions are closed. If that reason is valid (though it's arguable whether it is), it's not enough to demonstrate a relationship to the expertise of gaming enthusiasts.
The latter has nothing to do with gaming, enthusiasts or otherwise.
Second, there's the question of what problem—in the context of enthusiast gaming—knowing the font actually solves. It's just a fact, like knowing the default color of dialog boxes in Final Fantasy is blue. It doesn't help you do better in a game. It doesn't increase enjoyment of the game.
At its closest relationship to enthusiast gaming, it's trivia: something you can bring up at (really lame) parties to impress your friends. But I'd bet 10 trappbucks that they're asked because the asker wants to use the font somewhere else: on a website, in a collage, for a term paper, in their own game, whatever. Not gaming related.
Now, one might say "but Mark, you idiot, we have tons of trivia questions all over the place! They get dozens of upvotes! Double standard!" To which I would I respond, "Aha, but it's not just the fact that it's trivia: it's the fact that it's trivia and does not require or solicit the expertise of enthusiast gamers to answer."
That is, you have to look at a question holistically: if it happens to be something that probably doesn't help you in game but nevertheless tickles the specific expertise of gaming enthusiasts, it's usually okay here because it keeps our expert audience interested. These questions, I'd argue, do not.
The name that song questions
The third question, Christmas Song in "The Polynomial" - steamworks, isn't the same as identify-this-game nor the font identification questions but it nevertheless has its own problems:
First, it fails your criteria of "look at this thing, do you see this thing? Tell me what it is" as it doesn't show the thing, only a vague recollection of said thing. It should've provided a link to the specific trailer it's talking about (although agent86 provided it in his answer).
Second, it's attracted guesses for answers that are difficult (if not impossible) to verify. The answer agent86 gave was a guess/speculation, whereas Alexey's answer provided no rationale for its correctness, just a link to an anonymous SoundCloud page. In fact, when I did a Google search for "jingle final the polynomial", the second hit I found was another anonymous SoundCloud page.
While neither are sufficient by themselves to make a question off-topic, they are both individually indicative of the same types of problems identify-this-game had: the asker has not done their homework, leaving the community to take a guess and hope they read the asker's mind from the past. Together, I think they are enough to close the question as "not a real question".
