Regardless of genre, role-playing is ultimately an exercise in fantasy. We want to imagine that we are knights, or wizards, or vampires, or space marines. There is a cathartic release that comes from pretending to be something we are not, in a world unlike ours. That world may have drawbacks as well as advantages, but even the drawbacks are things that we enjoy imagining. We are intrigued by how different they are from the challenges of our own daily lives, and we rest in the knowledge that those drawbacks will disappear as soon as we step away from the table (or out of character, in the case of a LARP).
