These are some of the basic rules that I've made to use while Roleplaying. Of course, you should not feel at all weighed down by any rules if they in any way interfere with what you want to do as GM. In my group, we rarely follow all the rules, and I usually just make up stuff as we go along. We've found that getting the right feel, perhaps by breaking some rules, is a lot funner than adhering stictly to the rules.
