Price is what puts this in four star range. Two dollars is a steal for the buyer. When it was 15 dollars it was a rip off.
The setting book is adequate. It has everything necessary to play a campaign on Burroughs Mars and that is about it. Adequate is the watchword here. It defines pretty much the entire book. Burroughs fans can "get" this book, but it seems unlikely to me that anyone else would. I don't understand the addition of the Clone Wars Synthmen and the War of the Worlds cephalopods however.
Adequate does not rate a 15 dollar price tag.
But it is great for two dollars.
The art and stories are evocative and imaginative. The art was clean but lacked "slick" except in a couple of places. Some of the art was a bit juvenile, but this was a minor amount. Two pictures got in there that clearly needed to be edited before being put in the hands of young readers.
Overall a good deal at two dollars.
[4 of 5 Stars!]
