Names (possible spoilers)

I thought it was interesting that the two characters played by Damon and Krasinski had last names that they did. Before the "twist" Butler was the loyal servant of Global and Noble was fighting for a "noble" cause.
Butler also played a game called "Absolut Madness" a game where the participant is in a lopsided/loaded game where he doesn't have a chance to win. Everyone (Global) is in on it and is controlling everything. It is madness to participate in a game like that.
