I have not purchased SOB as of yet but fullly intend to. I keep seeing every one make the suggestion to cut the artwork out and want to say that I disagree. I have come to expect certain things from Hero and artwork in the products are one of them. I am more than willing to pay the extra for the artwork.
I'm in the same boat as a lot of other folks, cashflow. Shades of Black is now number three on my list of Hero Games products I will be purchasing next. Battlegrounds is currently number one. I think I will be getting SOB in the next month. I like the concept of what you have done with this. I will gladly buy more PDF products at a lower price than a book. I don't mind the time and cost of printing it out. Even though I will eventually have all the books Hero puts out it is a rare occasion I can run right out the day it is released and drop $20-25.
Those are some great maps. I always grab maps of parks, malls, houses, etc. whenever I go just to use them as maps for Champions. I have a huge collection just waiting to be put onto hex paper.
