Welcome, James. I haven't read your book yet, but I look forward to doing so. Have you read Land of Lisp? Are there other books you find particularly inspiring as they teach game development?
I've only seen the book in the bookstore but haven't read it. I've been looking more and more at the Game Design side of things lately. I'm reading A Theory of Fun for Game Design.
With a little knowledge, a cast iron skillet is non-stick and lasts a lifetime.
