What is Roleplaying? (Part II)

During the Grognardia drinking game, I suspect my readers have thrown back a few whenever the 1977 Dungeons & Dragons Basic Set edited by J. Eric Holmes is mentioned. Because it was my introduction to the hobby, I still have a special affection for it over all the other D&D products I've bought over the years. Looking back on it now, one of the more notable things about its rulebook is that it doesn't include an explicit section in which Holmes explains the nature of a roleplaying game. In fact, the word "roleplaying" (or "role playing") only appears in its text three times, one of them being on the title page. 

To some extent, this is understandable, since the Holmes rulebook hews very closely to the text of the original 1974 little brown books, where the word "roleplaying" does not (I think) appear at all. Aside from the aforementioned title page, the two other places where the word appears are the preface (by an unknown author) and the introduction (presumably by Holmes). Here's the relevant section of the preface:

That's pretty simple and straightforward. It also makes sense, given that, even in 1977, when this rulebook was first published, the concept of a roleplaying game was still a very new one, especially outside those already involved in the hobby. For a basic rulebook, one might well expect it to "introduc[e] the reader to the concepts of fantasy role playing." The introduction, meanwhile, simply calls Dungeons & Dragons as "a fantastic, exciting and imaginative game of role playing" before launching into an extended description of its play: It's not a bad description, but it's all a bit abstract in my opinion, particularly if you have no prior knowledge of what the actual play of the game might look like. I know that my friends and I were initially quite baffled by the nature of roleplaying, taking it to be closer to a strange new type of boardgame. Remember that we came to Dungeons & Dragons through Dungeon!, so I hope we can be forgiven our misapprehension. Furthermore, the title page of the Basic rulebook contains the following subtitle, which recalls the subtitle of the Little Brown Books: "Rules for Fantastic Medieval Role Playing Adventure Game Campaigns Playable with Paper and Pencil and Miniature Figures."
The section of the Holmes rulebook entitled "Dungeon Mastering as a Fine Art" does include an example of play that features a dialog between the referee and the party's caller. This goes some way toward elucidating the practical details of roleplaying, but it's still not very explicit about the subject. The AD&D Players Handbook is even less helpful in this regard, lacking even an example of play (though a very lengthy one does appear in the Dungeon Masters Guide). The 1981 version of Basic D&D, written by Tom Moldvay, contains what is probably the most famous example of play in the history of D&D, but its treatment of roleplaying as an activity is still quite vague in my opinion and, in any case, we started playing before that version of the game was published.
When my friends and I eventually came to understand what roleplaying was, it was no thanks to any rulebook we had read. Instead, our knowledge was imparted to us by a friend's older brother, who'd been playing D&D for a couple of years beforehand. Once we finally got it, it was very easy to look back at Holmes and see what he was attempting to explain, however unclearly. I suspect our experience was not unique. Unlike, say, the 1983 Frank Mentzer-penned version of the Basic Rulebook, which does an excellent job, in my opinion, of explaining the nature of a roleplaying game, I find it almost impossible to imagine anyone picking up Holmes and then being able to start playing without any confusion or need for clarification from someone who already knew how to roleplay. I say this as someone with great affection for the Holmes Basic Set.
Nowadays, I think it's much more common for RPGs to include explicit "what is roleplaying?" sections and examples of play. Even so, I can't help but wonder whether they're any more useful to people than were the sections with which my friends and I had to contend in our youth. Of course, the concept of roleplaying is now much more widely understood, with many popular computer and video games making use of the concept. This fact might make such sections almost superfluous in the 21st century. Nevertheless, I find myself wondering about it as I continue to work on Secrets of sha-Arthan. Is there still a need for a lengthy description of roleplaying in a contemporary RPG or is the need for it a thing of the past? This is something I've wondered about before, but enough time has passed since then that I'd curious to hear what readers have to think about the topic in 2024.
