After watching the story-identification tag, I noticed that many questions are of poor quality, simply because the information provided is very minimal.
This issue was already discussed here but the thread is already 3 or 4 years old.
The problem with low quality questions on this tag is, that it's just a guessing game. With too little information, the possible answers are too many to give a precise answer.
I'm somewhat active on anime/manga stackexchange and they have a special reason to mark a question as off topic because there is too little information. Questioned with enough votes are put on hold.
On the mentioned site is a checklist, of which at least three points should be covered by a question to be considered on topic.
The list covered following items:
- Any description of the leading/recurring character(s) (i.e. physical description, behavior, etc.)
- Any description of any distinctive features, including the plot and related elements (e.g. girls who are soda cans that do battle, or i.e., the setting, the plot)
- What the genre or cinematic style was (e.g. mecha, sci-fi, fantasy, shonen, shoujo, seinen, noir, cyberpunk, etc.)
- What the drawing/animation style is like
- When and where you saw it (if you saw it when you were a kid, don't give your age, give the approximate year, and month if possible)
- Who the publisher, licensor, and/or distributor was
- Type of media: TV show, OVA, movie, manga, web-series, one-shot, etc.
- Any image(s), audio, or video(s) related to the series (an exception may be made for questions with one or more of these items)
This answer also links to a second thread which lists following points:
- A complete description of one significant character: Hair color, eye color, skin tone, clothes, etc.
- A complete description of one significant location: Type of location (farm, house, etc.), style of location (colors, notable characteristics), etc.
- A complete description of a plot point: Detailed information about a story arc, central theme of an episode, or concept focused on
- Character's name (approximations are fine)
- Incomplete character descriptions: Gender, approximate hair style, etc.
- Type of media: OVA, TV show, serialized manga, one-shot, doujin, etc.
- Publisher, licensor, distributor, etc.
- Year you saw it (and month, if possible)
- Publication you read it in, or TV channel/network you saw it on
- What language your read/saw it in
- What kind of art style it has
Of course, answering three points doesn't automatically mean that the answer is of a higher quality. But the chances that we have enough information to narrow it down to a single instance are higher.
An example for such a question would be:
Last year, I read a Manga about a boy, coming into a school where they learn magic. At first nobody liked him, but later on, he became popular.
The problem with this question is, that the description isn't detailed enough. I can think of at least half a dozen mangas which cover all of this.
Almost all of the points in the lists can be adapted to SciFi work, that is not necessarily anime/manga.
