Legend
Part of the problem is that D&D (up to 4e) had seven races it used as core. (Half-orc disappeared for one edition in the middle, even further diminishing it). You have to go to 4e to get two new races in the PHB, and there is a highly resistant strain of DMs who cannot accept anything but the original PHB races (and let's be honest, gnomes and halflings are often ignored and half-elves and half-orcs defined by their lack of place in society. So we're really talking humans and elves with occasional dwarves). 50 years in and I still rarely see gnome or half-orc NPCs, let alone tieflings and Dragonborn. And a some fans throw hissy fits just seeing Dragonborn NPCs, because they are "too modern".I'm not talking about pop size.
I am 100% talking about lore prominence.
I've reached the point that I would prefer those elements shoved down every setting's throat, continuity be damned. I want Baldur's Gate to have a Dragonborn regiment. I want a tiefling mayor, and an aasimar pirate. I want tabaxi thieves, aarakroca acrobats (aarakrocabats?l and a gnome evil mastermind to rival a Bond supervillain. In Greyhawk. In Faerun and Krynn. In Ravenloft. And even in Athas. Make few exceptions for certain settings (like subbing kender for halflings on Krynn) and go nuts. I don't want the Star Wars cantina, I want the bloody galactic senate.
Let's break this habit of only having human NPCs and the occasional demihuman. Bring the menagerie.
