I honestly am having a difficulty of following the obfuscated use of "literary" in this thread. At times it seems equated variously with "text," "anything written" (not to be confused with 'text'), "narrative/story," "oral performance," "anything spoken/conversation," etc. The goal posts keep getting moved and obscured for the sake of claiming that whatever transpires in RPGs is "literature" or "literary." I can definitely sympathize with why [MENTION=85555]Bedrockgames[/MENTION] is frustrated by all of the equivocation that transpires in trying to justify RPG as literary.
I will say that attempting to claim TTRPGs as a literary endeavor shortchanges what makes TTRPGs unique as a storytelling medium. Yes, there will be overlap between TTRPG storytelling with literary storytelling, oral storytelling, performative storytelling, cinematic storytelling, video game storytelling, etc. Why? Because stories often follow patterns in human culture but many of these media are exceptionally new to human civilization (e.g., film, TV serials, comic books, video games, etc.), and we are only beginning to unravel how they are distinctive from prior modes of literature and theater. And I think that attempting to claim TTRPGs as a form of literature or as incorporating literary techniques (which some seem to equate to broader storytelling techniques) is attempting to turn TTRPGs into something that they are not.
