I have designed a light two-player storygame about Eowyn's adventures (following the War of the Ring, although it could just easily be set in her earlier life), with some input from Story Games folks in an earlier thread
I've already started playing it, and I think it's a really fun game. Uses Keys a la Blackbird/TSOY, and a fun but simple die mechanic inspired by Otherkind dice which gives a lot of "bang for the buck".
The game includes lots of adventure seeds and ideas, but requires an experienced and motivated GM.
If you're looking for a fun two-player game, take a look! The rules fit on about two pages, plus a character sheet."Thus began the Adventures of Eowyn..."
