Useful Blog Sources

While looking stuff over, I've found a pair of very useful blogs for game design in general.

http://bbrathwaite.wordpress.com/
Brenda Brathwaite is a teacher at the Savannah College of Art and Design, and she focuses particularly on game design.

http://gamedesignconcepts.wordpress.com/
Game Design Concepts is a blog run by Ian Schreiber, and is a blog used for a virtual classroom for game design. I've signed up for it, and do the assignments, though DAI505 is still my top priority.

Books I'm using so far include the following:
A Theory of Fun, by Raph Koster
The Art of Game Design: A Book of Lenses by Jesse Schell
Challenges for Game Designers by Brenda Brathwaite and Ian Schreiber
Rules of Play by Eric Zimmerman

And the Rules of Play reader.

I've found a large number of other articles and sources too.
