So I don't really care about these things anymore, but I was reading this article (and it's a very good one): Gamified Life.
In the article it mentions (without references):
Dice-based games of chance are thought to have originated with ancient divination practices involving thrown knucklebones.
So it's okay to play Yahtzee but not okay to go trick-or-treat. Both are only "fun and games." Both have ancient links to superstition (although one more overtly than the other). Yet one is okay and one is not. Related to this is how can they apply pagan/superstitious origins to many things but not to others. It's all very inconsistent.
These questions are more rhetorical than anything. They were an amusing thought I had when reading this sentence accompanied by relief I'm not longer in that cult.
