IMO, the big American bias in heroic fantasy RPG including D&D is how empty (most) settings are. If you travel (nowadays by car) in rural Europe, you'd find village every 5-10km, turns out that people walking to their field don't like to spend more than 1h commuting. While on some high fantasy map, you have like 3 day of walk through a dangerous forest, or an endless plain without much settlements.
Also it's worth mentioning that many European major roads/highway have been built at first by the Roman, and have been modernized through history. So again, middle age wasn't as empty, salvage as many D&D settings. Which indeed looks more like frontier era US.
And America wasn't actually empty frontier, either. It was full of the native people that had been living there since time imemorial, and the ex-europeans slaughtered and plagued their way through.
Considering ~95% of the native population died of disease within 50 years of the settlers landing? Yeah you can say it was pretty empty. I'm always fascinated by the willful ignorance of "settlers" in the context of the old west. Journals talk of "miraculous" groves of fruiting bushes and trees or other edible vegetation and how it's clearly a gift from their white god while studiously avoiding any mention of the signs of previous habitation in the area. We're still discovering massive irrigation networks in AZ and NM with satellite LiDAR that no "settler" ever mentioned.
Don't overlook the first genocide of my people by focusing too hard on the second. The Europeans struggled to quell the survivors. I honestly don't think settlers had much of a chance otherwise, even with the difference in technology.
I dont think that's American, it's a shit-ton of custom work to fill all that in. Are Europeans willing to spend 10 times as long worldbuilding their campaigns??
The Sword Coast setting is essentially a post-collapse setting where monsters are an existential threat (in theory). There are no longer villages every 5k because only the best and safest lands are worth farming.
In theory. Though I guess you could argue the Sword Coast is also kind of a metaphor for American colonization? The barbarian tribes certainly have Native American coding going on at times.
Interesting take. I look at it as less “anti-medieval” and more anti-government. Gygax was a libertarian and it grew out of wargaming. Gygax just wanted a world where he could fight dragons and didn’t bother to do the world building of an economic or political system. I think this was more out of disinterest in the topics rather than as a political stance.
