Legend
The idea that everything corresponds to real-world physics except when magic intervenes is completely ludicrous in the context of D&D, though. D&D worlds involve giants, dragons, beholders, undead, divine intervention, and multiple alternate planes of existence which are readily accessible. How can you possibly say that the rules of reality in a D&D world compare to ones in our world? I can't accidentally stumble into an alternate universe in my daily life, yet a D&D character can. I can't jump 30 feet into the air, but who is to say that a D&D character can't?
Its not ludicrous, and its what D&D has been lacking for 15 years now.
D&D needs to be (at its heart) mundane, and then let the exceptions change the mundanity. D&D goes really wonky when logic gets applied to it. Things like kings and knights and the feudal system get destroyed horribly in a GP economy where adventurers haul out huge sums of gold. Magic utterly destroys medieval warfare. Active pantheistic deities utterly redefine the relationship between mortals and divine. The world of D&D very quickly stops looking like our world and myths made real and starts quickly looking very foreign and very modern. (See: Eberron. D&D tropes taken to logical conclusions).
At a certain point, you have to accept mundane things. Tigers and not Feyshadow Tigers. Magic isn't common enough to turn the medieval infantry into guerrilla warriors with flamethrowers and grenades. Kings have rulership by divine right and nobody asks why. And a fighter is a trained dude in armor with a weapon who might be very deadly with it, but he's not breaking the laws of physics to do so.
Really, D&D has slowly drifted away from "Medieval world + magic" to "Magical world, with medieval tech." It would do well to go back and regain some of that feel.
