I've had my game materials examined by a contact who has published titles under their belt, and his main reservation is that my game relies on a lot of individual content. That content is time consuming and expensive to create, and doing so as a single developer would be difficult.
Right now I'm reevaluating the scope of the game, applying it's core principle to each proposed mechanic to distill it into the core experience I want to maintain. After that is complete, I will see if the project remains feasible.
Hurdles upon hurdles.
