what is your favorite game that origionated from a book?
To kick it off myself:
I guess it was pretty loosely-based on Lovecraftian themes, but I really enjoyed Call of Cthulhu: Dark Corners of the Earth. Great graphics, great gameplay, great design (sanity, blood, injuries and the like) and it had Dagon. That's a winner.
I thought the LoTR series was pretty good... nice graphics and gameplay.
