Inspired by a recent, and very brief, discussion on Twitter (nod to Kathleen Mercury and Paul Grogan), I decided to investigate the age old question of what makes a role-playing game a role-playing game. Now, let me say that this article is by no means exhaustive, and I am merely trying to touch on the main points only. Also, and this is sort of a spoiler, it turns out that the matter is unlikely to be settled any time soon, and different people have different views of what is a "true" role-playing game and what isn't, or what game is not a role-playing game, but has role-playing elements. Ultimately, of course, it doesn't matter whether a game is, or is not, a role-playing game, as long as you enjoy playing it and have fun with others or on your own. So bearing all of this in mind, let's start.
