If your leanings are towards gritty sword & sorcery, or you are tired of the usual pseudo-medieval worlds of most fantasy RPGs and are looking for something different, then look no further. This is a roleplaying game set in the ancient world of Mesopotamia around the time of Hammu-rapi (approximately 1767BCE).
The background material presented is very rich in detail, and it is clear to me that the author is expert in this period of history. The content refers to original Ancient Mesopotamian terms, and even provides the relevant cuneiform text! Impressive. In presenting the background, the author assumes that, whilst some players will want to play in a fantastical version of Mesopotamia, others will want something more historically authentic; both approaches appear catered for.
Although the game uses a somewhat altered version of Pathfinder/d20, it seems to me that part of the philosophy behind this book is that it will be used by players in their own preferred system. My view is that this work should be readily convertible to other systems, especially derivatives of d20 (my preference is for OSR type games, and I see no difficulty in conversion). Again, another feather in the hat of wider appeal.
In sum, there are few enough good RPG books out there set in Ancient Mesopotamia (others I would recommend being Ancient Kingdoms: Mesopotamia, and Testament), and this is a welcome addition. Given the rich detail this work contains, I consider it my 'go to' source for roleplaying in this historical era. It also has one of the best names for an RPG I’ve ever come across. Recommended!
