adventure books. Being a dwarf collector and gamer, I picked up one of the warfare books (the other two being on orcs and elves). The book is the usual style for Osprey - softback, a bit smaller than A4 size and 90 odd pages long.
The book is written in a semi factual style, the introduction explains that it is an examination of fantasy tropes. As you read through it becomes clear that Tolkien's influence (and thereby the Warhammer world) looms large, with a smattering of other backgrounds adding to the mix.
The first chapter covers dwarf origins and society, their deities and generally the way they live and integrate in the world. The second chapter looks into dwarf military life and discusses various troop types - the expected heavy infantry, crossbow, and war machines, with a smattering of more unusual types like bear cavalry and gnome woodwalkers (I suspect this comes from the D&D world but I'm no RPGer so could be wrong here).
These reservations aside, I enjoyed the book. It's not a long read, you can whiz through it in an hour or two. I am a bit puzzled as to the target audience. Warhammer and Lord of the Rings players have long and rich backgrounds to draw inspiration from, as presumably do players of other long established systems such as D&D, so it's not "needed" by them. Newcomers to fantasy gaming who do not relate to these worlds and have recently discovered a non-descriptive gaming system, such as Dragon Rampant, Mayhem, or Saga may well find it useful to have their dwarf army grounded in some lore. At a retail price of £10 it's not overly expensive, and certainly not much more than the cost of a couple of gaming magazines.
