1942-1943 Harback Rulebook - Flames Of War
This new rulebook has slimmed down by reducing the amount of unnecessary flavour text around the rules, and by dropping large numbers of special rules in favour of just stating their effect on the relevant unit cards.
These unit cards are the other obvious change in the new version. In the new army books, every unit has a card listing its ratings such as its motivation, its skill, and how hard it is to hit, along with its speed in different circumstances, its weapons characteristics, and on the back the unit organisation, points cost, and relevant special rules. Because each card shows the scores needed for that unit to succeed in various things, we were able to replace lots of rules with simple stat changes.
Despite the shorter rulebook and easier to learn and quicker to play system, the new version retains (and in many ways enhances) the tactical depth that drew players to earlier versions of the game.
