My friend sent me this link. I agree with all you have to say about DDA. And I'm totally against changing difficulty based on how player played. Before you read what my thesis is TRUELY about, please don't mix traditional DDA with my work. My thesis actually analyzes why traditional DDA doesn't work, and how to make a design adaptable to many different individuals.
