It's entirely open to modification for whatever purposes you'd like. Most of the SWN rules are designed such that they can be modified and adopted into entirely different things. I'll send you the PDF of faction rules so you can have a more comprehensive look.As great at it is to have a willing DM for this kind of stuff, I'm worried that having such an in depth system might take away from some of the freeform RP appeal of past NationStates projects. Is there a stripped down version of what you're proposing?
