I would like the ability to start games with no enforced NAPs. I don't mind if people make treaties - I just think that enforcing them from on high seems out of place.
(My reasoning: If people in a real world had a NAP, there would be nothing preventing them from breaking it, except the fact that they would get a bad reputation. I'd love NAPs that were breakable (sneak attacks, etc.) but the fact that the player broke the NAP was announced to the world.)
