A NAP is what you and the person you make the agreement with perceive it to be. If you both have different views on what it is, that is great stuff because that means it is going to lead to conflict. Dominions is not a game of obtaining world peace.
Last night I introduced three of my buddies to the game through a demo game blitz. None of them had ever been to this forum and not a one of them could tell you what a NAP is. Consequently, they attacked anyone and everyone that did not have the same flag as them
. In the end everyone had a blast, and it reminded me of how fun this game can be when there are no player created restraints.
