Books For RPG Design

[Davaris]

I'm finding it difficult to find good books about game design. What I am interested in is what makes good quests, what makes characters interesting and how to make them grow. How to create stimulating game mechanics (mathematics of RPG quests/rule systems) and so on. So with the forum mods permission, I'd like to post a couple of books I know about and if anyone else has come across others, please post them as well.

The books I know about are:

 

GM MASTERY NPC Essentials

 

Dungeon Master's Design Kit

 

Design Patterns of Successful Role-Playing Games

 

Quests: Design, Theory, and History in Games and Narratives

(I have this on order and hope it will be good)

 

 

 

I hope there are more out there. . .
