This is a thread I could go into a very large amount of detail in, but it's been progressively drawn to my attention that a lot of (though not all) people here don't appreciate the "long-winded" walls of text I toss out in order to make sure my responses are detailed and thorough.

I will say that there's nothing [i]wrong[/i] with having a complicated world (contrary to some belief, since whether this is right or wrong is entirely [i]subjective[/i]) in my eyes, so long as you can avoid having plot holes and contradictions; a good portion of the notes I have for my main story project are centred around preventing these sorts of problems.

If you'd like excessive detail in the form of a much bigger response, I'd like to request you either ask me over PM or request for it here directly by giving me the basic idea of the style/genre/etc of story that you would want to create a world around; it's much easier to tell you how you could approach an idea if I have some sort of premise for it.

What I will make a point of regarding the thread topic is this; the concept of a "stagnant" idea is not only a matter of opinion and preference, but there's also no such thing are true one hundred percent "originality", so I think you should focus less on having a [i]new[/i] idea and more on having a [i]good[/i] (well thought out) idea. Everything draws its inspiration from something; for example, many people on this very website frequently bash anime like a bunch of blind bigots despite the genre inspiring and contributing to a vast amount of art and fiction; whether those bashing it are people who aren't able to work that out or are those who simply choose to ignore it out of self-ordained ignorance is entirely a matter of the individual though. Everything draws inspiration from something; the idea of pantheons of gods existed in mythology long before it did in fiction.

It might seem as though I'm somewhat stating the obvious with this diatribe, but the point I'm trying to make is that there's no such thing as actually having a completely original idea. What actually defines "originality" is taking a concept that already exists and doing something creative and interesting [i]with[/i] it. The idea itself is seldom ever the problem, but rather how it's presented. Therefore, I don't think you should focus on whether or not your idea is completely new or not; an overt fixation on originality can actually hinder a person's work. While my own project is very unique in some ways I do not create my world deliberately trying to be different; if the ideas that are appealing to me happen to be unique then fair enough, but my goal is to write them well and make sure they are engaging, compelling, thorough, deep, complex, and detailed; all things which are more important than being "fresh".
