Publication History for THW

The Two Hour Wargames range has been developing for over ten years. Chain Reaction 3.0 represents the most current thinking on the underlying rule mechanisms. When considering which of their commercial rules to buy I’m interested in how old they are; the older the rules the more out-of-date they will be. For example, Legends of Araby (2003) uses d10 whereas Chain Reaction 3.0 uses d6.

This publication history is based on an email from THW on the progression of the games and the news section of the Two Hour Wargames site.
