From the introduction:
The NUELOW design team recognizes that regardless of the role-playing game system being used, player characters will invariably engage in lecherous behavior and the odd romantic pursuit. In most game systems, Game Masters have to rely on their own limited experience with lechery to give the characters what they want. That is, after all, the only way to please the character's player, and isn't that what the game is ultimately about?
But NUELOW doesn't abandon the GM. Instead, this game merely provides a framework within which gamers can "play house" with imaginary people, a way to ensure that everyone's playing the same game. We provide ideas for how to handle love (in both the carnal and ideal sense) within the context of a role-playing game.
