Saul when running his D&D games has never allowed Evil Characters or Assassins. Though Saul had this rule he didn't have to enforce for 25 years as a GM. Many GMs often have limits in their games. GM's often restrict such things as certain races, Alignments, Classes, "broken characters" and many other reasons in many different games.
Saul and Jolene discuss this topic in this episode. Is it good, bad and how is the best way to deal with players that want to play those things that are on the "No Play' list.
