IMO the main motivation for creating a custom story, any video game, or any form of art for that matter is a desire to communicate, and share an idea, or story you have a passion for with the world.

With this sort of motivation in mind, you should have the sufficient amount of motivation to do the project. Sure more people caring about the project can boost this, but it will never be comparable to the motivation you induce on yourself - the desire to share your project with the world.

If you have that, then I'd say screw how many people care about your work. As long as you know what you're doing is good, accept criticism from the people who do care, your project will turn out awesome. You need not a enormous fanbase to keep development moving.
