Exactly!D&D also has instances of six-shooters, tanks, The Land Beyond The Magic Mirror, the Amazing Drider Man, King Kong, Monkey Magic, trips to modern day earth, a Cat Lord who looks like he might start singing Billy Jean any moment now, and Boccob knows what else.
Why? Because you don't like the fact that my impression of D&D is influenced by the above-mentioned game elements you just mentioned?All of this is a furphy.
These nutty outlier things are a part of what defines D&D fantasy -- the kitchen-sinkiness of it, the free-for-all nature of it-- and separates it from a hypothetical RPG that's more focused on strict genre-emulation.D&D is no more defined by six-shooters than it is by lasers.
Except for the things like martial artists straight out of 1970's kung-fu movies (quivering palm of death and all) and gelatinous cubes (ie, the acidic Jello).What it IS defined by is the default core implied setting, which has none of this, and is thoroughly pseudo-medieval.
I'm giving you my impression of D&D, illustrated by some details that you don't dispute...So he's right, and you're just playing games.
... look, if you ignore everything in D&D that isn't medieval, then D&D is a medieval game.
