Published by Nordic Weasel Games, Not Just a Brush War. Brush war campaigns for any war game system is apparently a departure from their usual product range, in that it is system agnostic and not designed to work specifically with one or more of its other products.
It is clearly aimed at wargamers, specifically those wargamers focusing on the brush wars of the last century, this century and the near future. The pdf has twos ections. The first section consists of tables for generating "imagi-Nations" for wargaming, these tables cover about 10 pages and are designed to be modularm, so that a player need not use all of the tables if desired. The last section is about 28 pages long and covers campaign rules, designed to overlay your wargames rules, again, they are modular and you need not use them all.
While not aimed at Sci-fi (my favourite genre) I can definitely find a use for this pdf in both my wargaming and roleplaying games. There are even rules for figuring the relative tech level of the imagi-Nation and a table for generating the name of military operations, I rather like this table and will definitely use it a lot.
I'd definitely recommend it.
I deducted one rating point, only because it is not broadly useful across all game genres. Having said that it would still be fairly easy to adapt it to your favourite genre.
