Flight from the Dark (Lone Wolf, Book 1)
pretty good, but ultimately not nearly as much fun as the fighting fantasy series. I think these gamebooks work much better when they're a little tongue in cheek, although having said that I tend to remember playing some of the Tunnels and Trolls books and enjoying them immensely. They were a bit more involved than FF too, still remember a little humour though as far as I can remember.
