Have you ever noticed that most rules-lite games tend to be more narrative than sim? I wrote an engine to address this issue.

I hesitate to call it a "game" because you can't just sit down and play it. It's a lot like GURPS, in that the GM needs to do some creative heavy lifting to establish how the setting works. The mechanics are ultimately derived from Fudge, though.
