Make some saving throws
I started off this post discussing the vampire pajama party, so I do not feel like I need to over-explain the idea that if your campaign gets silly, it might be time to reset. However, I do want to mention that the vampire PJ -fest is a mild example of games getting silly when running long in the tooth. I have seen a group of role players decide their characters would play another tabletop game in character. So, a group of Azeroth's finest got together to role the dice and make some saving throws and buying Granado Espada vis from us.
