It’s no secret that the Next War Series incorporates variations of mechanics from other distinguished games. One of those games is Mark Herman’s Flashpoint: Golan (FpG). I contacted Mark during the design and development of Next War: Korea regarding using a version of FpG’s International Posture Matrix, and he graciously agreed. There are differences, naturally, in the execution, and the Matrix is evolving even further in Next War: Taiwan. The intent, however, remains the same: it provides a method for players to randomly determine the effects of international influence in the primary operational area. Of course, players are always free to experiment with simply assigning Intervention Levels to explore various “what if” scenarios of their own devising.
Use of the Matrix requires a player, usually the attacked side, to roll a die to determine the sentiment of three “factions” of a particular nation: the Administration (i.e., executive and/or legislative branches), the Military, and the Popular Vote (i.e., the willingness of the people). Each faction can end up in one of the three Postures: Passive, Moderate, or Aggressive. Each Posture has an assigned value (-1, 0, +1 respectively), and the player simply adds each faction’s Posture value to generate a Posture Sum. This Posture Sum is then compared to a table to determine the overall National Posture: Passive, Moderate, or Aggressive. This National Posture is, finally, cross-referenced against the particular scenario and generates an Intervention Level. While it sounds complicated, it probably took more time for you to read how to do it then it takes to do it.
The secret sauce, if you will, is in determining which nations would or can intervene and at what levels would they intervene given enough provocation as represented by the various scenarios. The general underlying assumption is that the longer a particular nation has had to consider the issue at hand, the more likely they are to intervene at higher levels.
