What is this?

I am beautiful. Dammit. 

Since I was 12 years old, I've read and played various roleplaying games. For that same length of time, I've written my own content for them and at various times, thought I was really good at it. Feeling particularly good about myself concerning various things is not limited to RPGs. I think I'm beautiful, super smart, and that everyone loves me.

Well, it turns out that none of the above is true.

After all the weeping and self-loathing wore off, I decided to solve the most important of the dichotomies: I'm going to delve into my favorite RPG supplements, break down what I like about them, and extract whatever knowledge I can from the design process for my own selfish use. The plan is to post this secret wisdom here, where no one in their right mind will find it.

With this knowledge, I'll become the greatest RPG designer in the world. I'll then be beautiful, super-smart and everyone will love me. Problems? Solved.
