This core has a ton of potential, but WFRP takes the crunch to an extreme that pushes it out of my personal preference. Zweihander does a terrific job of abstracting the subsystems of WFRP, but the header hierarchy of the Revised book isn't clear on sight read.

I'll give an example here; "Professions" is the Chapter Header, "Buying Character Advances" is a H1, "What is a Tier?" is a H2. They're all the same color and similar size, and the Center Alignment of H1 can sometimes appear as a Left Alignment when the text is longer.
