4. Will the campaign be libertarian propaganda?
No. But I will endeavour to depict the campaign as realistic according to my understanding of history and human behaviour (but not so realistic as to preclude entertainment; playability takes precedence). This includes force relations and economic issues. Nobody in my campaign is a libertarian, and libertarianism does not exist there. However, players who want their characters to become merchants or who involve themselves in the economy will witness market behaviour, and it would be impossible for me to present things except as I see them. Also, there is nothing mysterious about the libertarian view of the market: we agree with mainstream thinkers that demand and supply are central to economic activity. This does not mean that capitalist characters will succeed by any means, for aggression is common and it can always bring instability and upset plans--and this is resolved according to conventional game mechanics (i.e., combat). Players need not fear my views; in fact, it is doubtful that they will be noticeable. Besides, every GM has opinions about how the world works, even if they're not systematic. Finally, I can't even conceive what a "libertarian spin" might be. Political entities in my campaign are not libertarian; rather, they are feudal, imperial, bureaucratic, tyrannical, etc.
