Being real? I appreciate the ppst, but that article is pretty crap. I've been playing ttrpg games since the eighties, depending on exactly how you define things. I've been forever DM for most of that.
I have literally never had a conversation about rpgs that mentioned any of that. The first one in particular is a given anyway, because they're games. Even improv has one rule.
Again, glad you posted it because despite thinking the article is crap, it was enough to start a discussion anyway :)
