Ceti, I agree. For reading, good sci fi trounces any and all fantasy contenders (pretenders?). Still, some fantasy is worth a look. Like Zelazny's Amber series. Of course, Zelazny was a sci-fi author, so it's natural he'd kick the pants off the fantasy genre at its own game.
But WOW am I off-topic...
Uhhh, uhhh.... ACD, yeah! Were there many (any) RPGs that could put the ACD to work?
