This is very impressive, and left me longing for more!

I'm not sure this is the direction you want to take, but I'll throw the idea in anyway. The format seems perfect to allow for user-made extensions:

- Content creation requires lots of work, but the kind of work that many are able to pull of, unlike videogame-like artwork.

- Being web-based, it should be possible to just link to new content: no need for downloads, plugins, etc.

Combining these two, you could pull off a kind of "wikipedia-like" game. I'm envisioning a game where there is a "known world" (where you enter initially). This would be your content. At the edges, you can venture into the uncharted parts of the world (link to people-contributed content/worlds/adventures). These outward links could be randomized among user-submitted worlds. If some of those worlds becomes so good you want to officially sanction it, you can then announce it as "charted" and incorporate it to the known world, with a permanent non-random entry point.

In my head, this would be very good because it would let you focus on the mechanic possibilities (which you seem to enjoy the most), freeing you from the content creation task while still building interesting game(s).
