First World War Campaigns - Optional Rules

[Volcano Man]

The default rules are how that particular game is intended to be played. These optional rules might vary from game to game depending on time period -- they are specific to the individual title, not the series (although I think they are common so far). With the default rules on, then you know that you are getting the intended experience. If you adjust them then you just have to be aware that you are adjusting how the game plays, and your experience may vary.

Other than that, choose which rules you want to use at your own discretion. Explicit Supply is one that is a personal preference thing.
