I like the books made by James Clavell about old Japan and Hong Kong... sort of epic and a good insight into feudal Japan and mid 20th century Hong Kong and other Asian countries. I also like the book AZTEC.
Jacob's Ladder was pretty creepy. I also liked IT and Pennywise the clown. After all these years, Pennywise still gives me the creeps, and I'm still apprehensive whenever near clowns.
It would be a nice addition, but it would wreck lore, and in the end, wow would still be the same. Addition of another faction would not change the essentials of what the game is. Raiding would still occur, arena etc. Of course it would be cool.
I liked some of the older SNES games that I never got to experience. I played through them with an emulator for hours of countless fun. I was more of a pc rpg guy, and I liked the BG series and Fallout series the best out of the pc rpgs.
