For the record.
I more a "consumer" than a contributor. Actually I'm eager to contribute but rarely find the chance, here are very knowledgeable users and when not knowledgeable they compensate being terribly good at researching.
I hope I can start to contribute more after I finish my online astronomy course, feel free to ask for the link if you are curious.
If you want to understand my use case, that I guess falls in a group that should not be less than 10% of users, I would describe it as:
So far, I formulated questions centering in space settings, but I read a lot of questions and answers from other areas. I guess I have read all "threads" about building dragons.
I formulate questions like they are for storytelling. And this won't change, probably.
I, in fact, write stories. But never with the intention of made any of them public. These stories are always for video game projects. Most of them will never be completed. And not necessarily the full story. I may take only the setting or the setting plus some concepts but then change names, places, and even role genres. Also for some exercises that may or not be used for a video game in the future. If you are curious, I usually use the notes format, with a lot of random thoughts here and there, and more rarely I write in novel format, with dialogues, scene descriptions and everything. Never with hand, always using software.
I often do a lot of reality check and believability check. Before I discovered the Q&A format I would do a lot of googling around different related things trying to measure the level of believability of a certain idea.
Believability is no what hurts suspension of disbelief the most, or well doesn't have to be. It's more art than science. Done right, nobody cares about believabililty, but I care a lot. Every time you hurt believability you have to give something as compensation, and if there is not enough compensation then people start to care. Compensation can be in the form of visual quality, character personalities and their overall design, etc. But depending where you hurt believability those may not save you.
In brief, worldbuilding can't be neglected. This place has a perfect name, I started to use that word a lot since I landed here. The translation doesn't sound right or practical in my natural language (can't be made into a single word), because of that in the past I used a bunch of different words to describe what we have for worldbuilding. Now I just put a "worldbuilding", without translating it, here and there.
