I was hesitant at first, thinking this was just another run of the mill gm aid, but the positive reviews convinced me to try it. Wow! Am I glad I did. It really hits the sweet spot for me as an world/adventure building aid without being too exhaustive or too brief. Not only are there all these tables to either pick from (or of course roll randomly), but you get some nice worksheets to build your world. The hex crawl work sheet and settlement work sheets are great to print out by the stack and get to really building your own world. I don't even own a d30! So if you don't have one, don't worry about it. It's inspiring to just read the lists and choose what you want to. Still, I now feel the need to buy me a d30! Excellent product that really feels old school, from the tables, the art, all the way to the choice of fonts. Highly recommended.
