Awesome! I enjoy Sanderson's work. Would be so cool.
However...
I'd rather have The First Law video game adaptation, in terms of my personal fantasy novel turned video game wishlist.
Joe Abercrombie is an avid video game fan that often details and records his latest playthroughs on his blogs. He'd be perfect and probably also highly willing to collaborate.
Imagine playing Logen Ninefingers, or an Eater, or Monza Murcatto. Sigh, a pipe-dream...
Another role-playing game crack at Game of Thrones would be epic, too.
TIP: Logen can channel his rage into short bursts of invincibility and super-strength. Build up your Bloody Nine meter and press X to trigger!
