Every time I cover the events in the PEL, I always mention the Herero War scenarios. I do this for multiple reasons (1) it's a labor of love for the authors, and after just my little foray into Samoa, I empathize with them (2) the Herero War is a German colonial conflict, and that hits my sweet spot and (3) the games at the cons are very basic, yet look great, and everyone has a great time.
After more years than I wish to recall, Roy Jones, Jr and Eric Alvarado finally have their definitive scenario book in print through Recreational Conflict.
The book is 184 pages and covers the history of the conflict, a set of rules for the era, largely based off of The Sword and the Flame, and thirteen scenarios. It's a decent size small press book for $36, when much thinner books fetch $20-25.
Fun gnome-related fact: Eric Alvarado is the inspiration behind the Captain Alvarado character who leads the Gnome Pirates.
