I think that your interest check would benefit from an abbreviated version of your Google doc here on this page. Just some quick summaries about your races and concepts that would give players a chance to form ideas without having to go out of their way. To give better form their idea, they can go ahead and delve into the doc to research. Also, speaking personally, I haven't read any of the fiction you listed above so the references are a little lost on me, but I can understand if you're trying to attract a crowd with similar reading interests. Clearly you've put a lot of work into this, and I'd like to see your RP take off the way you want it to. Making it digestible to players is a good way of doing it. Using the Doc as a reference sheet instead of required reading will ensure that all of your material is properly appreciated. With that said I'm intrigued by such a detailed world. What do you have in mind for a starting plot?
