Once I feel that my ability to solo is completely gone, I have no qualms with voting draw. That could mean that I'm small and dying, reaching a stalemate position, or merely at a point where there a few other powers of similar size unwilling to play draw and open themselves up to the possibility of victory, thereby giving everyone a chance. When you play with top players, people are usually too smart to let each other get into soloing positions, so most solos either result from a bad egg skewing the game in favor of the players he interacts with most or loss of logical reasoning due to clashes of the massive egos that are sure to accompany most people who are good at a game such as this one. It's really hard to win a game of diplomacy, and that's why it's so much fun.
That said, there are some players who completely destroy such an argument (see TheHangedMan, he's magic) with their amazing soloing abilities, and others who do lack the proper drive to solo and lead to boring games. And then there's Octavious, who knows how to settle for a draw in style. That is, by utterly humiliating me first:
