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.
