I agree this kind of setting is nothing to do with reality -- it's the literary equivalent of the castles in Holly wood films which are all cavernous halls and huge bedrooms -- but I'm on a one-woman crusade to nudge writers into bringing some elements of reality to fantasy!
To me, it's akin to the argument about what's more important -- a good plot or good writing. I want both! I don't expect anyone to spend years researching medieval history to get everything 100% accurate (which most so-called historical novels certainly don't manage!). But with all due respect to jjcomet and anyone else writing this D&D-like stuff I can't understand why someone
wouldn't want to elevate his/her work and make it stand out from the crowd by thinking more seriously about food and customs and agriculture and trade and how it all fits together in world-building, rather than taking a somewhat naive view of what people eat and how they build their homes or clothe themselves.
It's not rocket science (if it were, then I'd be wholly at sea!) -- it's simply a matter of questioning assumptions, thinking a little more deeply, and looking a few things up. We want our characters to feel real rather than cartoonish cardboard cut outs, so why shouldn't we want their background to feel real, too?!
And on a more serious note, history is having a hard time around the world at the moment, with demagogues of all stripes re-writing it to suit their political ends and the mass of the population just accept what is being said without critical thinking or any research. Adding a byknife into an adventurer's hand in a D&D fantasy might not protect us from all that, but who knows, it might just get someone asking a question, which leads on to more questions, more answers and some actual
thinking, which is never a bad thing.
And with apologies to jjcomet for taking this off-topic, here endeth today's lecture on my History Rules Manifesto!
