I will commend that the book is thorough and covers a broad range of topics that will significantly help take your game beyond dungeon dives, I just wish it was useful without spending the cost of this book multiple times.

This is a great reference for Adventures Dark and Deep. For other OSR systems it is only useful if you have or plan on buying other entries in the ADAD line. The concept of more rooted, less murder-hobo campaigns is great and the execution in this book is very solid, but it is advertised as being compatible with other osr games, which I believe is misleading, because this is not a stand alone product. There are 36 references to other books for information, making this book a supplement more than a stand-alone product. This kind of cross referencing is bad in any event even if I owned the whole line.

Adventures Great and Glorious is an impressive volume of work. It is designed for use in a higher level campaign, with some mechanisms that transcent level. I see opportunities to use this resource for any campaign that involves settlement, governance, or estates. It is targeted at OSR games, but I would use large portions of it for my GURPS or Rolemaster campaigns.

I have never purchased anything by BRW games, but I like what I see. The tables are orderly, with effective and topical illustrations. The economics seem balanced, but I have not performed an in-depth analysis. All in all, based on this product, I would buy more of the author's work.
