Oh god, yes please!

Also Malazan: 

Would make for a stunning game. 

I would like a fully realised Warhammer Horus Heresy game and preferrably made by the Creative Assembly. So a hybrid turn based management and realtime combat game just like the rest of the total war series of games.

Doubt this will ever happen but the fact that the Creative assembly will be doing the Warhammer fantasy game gives me some hope.

The Hunger Games is terrible, Battle Royale would be much better. Though I can barely imagine the shitstorm a game version of it would cause seeing what the movie did.

Wonderbook

Not because those ones are pretty hard to configure, the graphic quality has to be more special and real for these ones.
I prefer “Behind the Beautiful Forevers” turned in to a game.

Lord of the Rings. There were a couple of old PC ones that were good for the time, but were REALLY limited by technology.

For the most part Lord of the Rings games of late have been based around the film, but the book world is much richer.

Personally, I don't see how either could be any better than a bad version of the worst version of Twisted Metal.

I haven't read either book, but I saw the movies. The movie Battle Royale had an amateurish plot that seemed like it was written by a 14 year old, and directed by a hung-over John Carpenter fan. Hunger Games was significantly better, and seemed to have a much wider scope that could be expanded to a much broader level than just the battlefield itself.

Ranger's Apprentice
Good story and would be awesome as game(s)

Just some worth considering:

World War Z
Hyperion, all 4 books
The Stormlight archive (Way of Kings)
