I'm working on a world that I'd like to make into a video game someday. I'd like a place to post information about it so I can get feedback, suggestions, etc. Is this the place for that? If not, where might a good place be?
NO ... but ...
I've merged this into the answer I gave to a similar Meta query a while back.
The long and short of it is you should be seeking this kind of advice & feedback on what's known as a "long form discussion forum"; or, for quick advice questions, you could also try a "short form discussion forum".
For the latter, Reddit is best. There are a lot of fantasy & sci-fi worldbuilding forums as well as gaming forums that cater to a worldbuilding perspective. You could try Fantasy Worldbuilding, or for a broader scope, Worldbuilding.
And of course, when you've got some tidbit of lore a bit polished up, feel free to submit it to the Universe Factory!
Stack Excahnge is specifically designed to help you with relatively narrowly focused worldbuilding queries. See What is Worldbuilding All About? We'd love for you to hang around, get to know this forum better and by all means, whenever you're facing a sticky worldbuilding problem, by all means ask here! Check out our Catalogue of Question Types to help you understand what we mean.
