Book turned Videogame?

[Gravy Devil]

If you could choose a favorite book to turn into a videogame, what book would it be and what style of game would it be(FPS,RPG,etc)?
"Enders Game" by O.S.Card as an Action/FPS
"Do Androids Dream of Electronic Sheep"(or maybe just a Bladerunner sequel) as an Action/FPS
"Edgeville" by Will Shetterly as a RPG

I'm pretty sure there's a thread of this already.
