Whether we are aware of it or not, our upbringing and life experiences have a dramatic influence on our perceptions. We carry those preconceptions into the fictional gaming worlds and then impose our preconceptions onto the world to make them fit our understanding. Not only are these preconceived ideas at odds with many game worlds, they can wash out the true colour and wonder of the worlds in which we game. Instead, we should seek to make each game world feel like a new vibrant world filled with new experience, rather than a collection of comfortable tropes.
Whether you are Jewish, Wiccan or otherwise, December tends to be a special time for many religions. In fact, a great many of the special events in a year are connected with religions. Not just special events either, but laws, moral values, communication, and countless things are influenced on a daily basis by religions.
However, in many RPG systems religion is chosen based solely on what it might grant a character. What I’m saying is that religions are very poorly represented in most systems, acting as little more than a statistic on a character sheet. While I don’t think there is a place in RPGs for real life dogma, I do think more time needs to be spent to properly highlight the influence and power religions have on daily life.
