As a GM, one of the greatest things that I found kept me back when I first started trying to provide a gaming experience to my players was my desire to create an “original experience” for them.
This led to a number of things that didn’t work: trying too hard to be original can mean that you reject the useful methods of the past that have been proven successful, and it can also mean that to compensate for the lack of existing material, you simply pass over into the realm of spectacle.
