Think of it like a great idea for a movie, or a book.
If you just have an idea for the basics or a twist on a genre, then that by itself isn’t worth anything really. But if you wanted to go ahead and explore your idea far enough to write a screenplay, or storyboard, or write character bios, that would be further along and may be enough to get your idea rolling. Just understand a great script or storyboard is still nowhere near being a great movie and so people will value it accordingly.
If you believe in it, and don’t have outside resources, then take it as far as you can yourself and then try to get it in front of someone who can help you take it one step further.
But if you’ve given it less than an hour, people who spend years making their own ideas a reality aren’t going to treat it like it’s gold.
