It makes me feel happy and determined about how well I've done at maintaining my D&D game. There have been some occasional lapses; sometimes when I've felt unprepared, we've had a smackdown or canceled a session. And we've certainly canceled sessions in the face of scheduling conflicts. However, on the whole, I feel we've done an excellent job of maintaining a regular schedule of play.
I think that this rigor has been a good thing for me. It would be very easy for me to say, "I'm not completely prepared, game canceled until I am," and turn that into never playing at all. With all my preparation problems, this game has the virtue of actually being played, and that's a mighty virtue indeed.
