“When Technology Meets Tradition” is a set of rules for wargaming early modern warfare conflicts, roughly from 1895-1915. The emphasis of the author is on early World War I (1914-1915) but other period wars are also of interest, such as the Russo-Japanese War or the Boer wars. The rules are fast-play and focus on the problems faced by military tacticians during early modern warfare: when outdated linear tactics and love of the offensive ran head-on into lethal, accurate, and rapid firing weaponry.

Schwerpunkt Rules for Warfare in the Age of the Rifle
Schwerpunkt is a set of free wargames rules for conflicts from the late 19th through the 20th centuries.. The author writes:
Schwerpunkt is a set of rules I designed myself before I bought CLA. Basically I asked myself what I wanted in a wargame and came up with the following criteria:
1) It had to be fast Playing
2) It should be capable of producing historical results
3) It had to be fun
With this in mind, I set about using all the rulesets I have ever played or read to come up with what I liked and didn’t like.
