Sequels, adaptations, remakes, revivals, etc

[Albertosaurus Rex]

I have never read any of The Wheel of Time either, but I feel that it's a slightly different situation. WoT has as I understand it, a continuous storyline that was building toward an ending. That someone should finish the story after Jordan's death is something I can understand, especially given the fact that he left detailed notes. Fafhrd and the Gray Mouser, however, is just a series of mostly unrelated adventures. That there is a sequel to that series feel bit off to me. (I'll probably read it anyway, just to see if it's any good.)
