I'd actively remove the standard races and replace them with some of the ones here. Including humans..
But I grew up with Tunnels and Trolls *and* RuneQuest...
I'd love a game with more trolls and gnomes and shadar-kai, and no or very few humans.
In addition to the setting I posted about above, I'm building a whole game set in an alternate Earth where magic, and supernatural races, are real, and hidden, and there are 9 "Worlds" which all intersect via Crossroads, which are waypoints where the savvy, or unlucky, person can step from one world to another. In that world, the classic relationship of Knight, Monster, and Damsel, is upended in terms of who plays what role. The trolls, the villagers, or the wandering fighter/hunter could each be any of the other three, and sometimes there is no "monster", and the only way to resolve the situation and "save the day" is to realize that.
It's a lot of fun to explore what being a hero means in a world where people have false expectations of what a hero looks like, and it allows us to play with a lot of otherwise really tough issues, by viewing them through a fantastical lense. Which for me, has always been the point of Fantasy. To use a foreign lense to give a different perspective on issues that are just hard to think about without your judgement being clouded by cultural, personal, and other biases.
But at the end of the day, it's a game about saving a world that is worth saving from a variety of threats, including a horde of "Demons"* whose prisons have been weakened by stuff that would take too long to explain in this post right now, about saving people's lives, exploring a fantastical set of worlds, building a better future, and leaving your mark upon history. With trolls and gnomes and Puca, and goblins that are actually lost kids who have found a home in Goblin Town. And playable angels called Watchers.
And I mean, you can play a human, too, if you want. lol
*(the game treats Demons, Titons, Jotuns, etc, as beings that existed as part of the primordial universe before the Big Bang, and who shaped the universe, or helped shape it, and then were defeated and locked away by slightly younger beings who we call Gods. as in Greek and Norse myth, some of these First Gods are on the side of the younger gods, and some have even joined their families, like Loki. Yes, Loki is basically an Elder God. And so is Thor's mom)
