Closing Thoughts. This is mostly a reprint of the mass combat rules from War of the River Kings adventure from the Kingmaker AP. I looked at the two of them, there is roughly 5 pages of stuff in the AP. This book minus OGL, sheet, cover and art. Has roughly 8 pages. Which is a couple of pages of extra stuff. I didn't notice any obvious errors and the art is fair black and white art. The layout is clean and very print friendly. This is a tough one to rate. While most of the information is reprinted and slightly reworded, some of it is new. If you have the AP with the information this gives you a print friendly way to print out just that information and it has a little extra. For those people it is likely a 1-3 rating depending on how important it is to have a print friendly copy. For those that don't have that AP then this would be all new stuff and a lot more useful, in which case I would likely give it a 3-3.5 rating.
So in short if you don't have the AP in question and you want some simple quick mass combat rules this is worth picking up, then I would give it a 3.5. If you do have that AP and would like a little extra and a print friendly version then it is still worth two bucks but not as good of a bargain then, then I would rate it a 3. If you have the AP and have no use for printing it out, then likely this is a product for you, in which case it is a 2. Most of the extra information is sample armies but not all of it.
