I collect role-playing campaign settings for this very reason. I love just reading through long geographies of made up worlds. Pouring over the maps. Imagining the geopolitical landscapes or how the alternative histories or technologies might function in that world.

I don't actually play role-playing games at all anymore. But it's an entire genre of work (made up geographies, bestiaries, etc.) that isn't really served outside of games very much.

There's a niche for a completely new type of fiction on the Internet. Creating a world through a wiki style website. Readers explore by searching for phrases or following hyperlinks instead of going linearly from start to beginning. I've spent hours at a time reading things like the star wars wiki, Depp diving to solve my own questions like "where did the sith originally come from?" or "can you have a black lightsaber?"

For me, the SCP Foundation (http://www.scp-wiki.net) gives that kind of feel, with different cases linking to one another. (SCP Foundation is a collective storytelling wiki about an organization that deals with the strange, mysterious, and horrifying.)
