"you can pick your differential" in Dragon Age (including the existing limitation, Dwarf can't cast magic etc.)
But still shit.
Imagine Morrowind with this awful "everything must be equal". the game would be shit.
dwarves
In D&D, there is a thing called "Mul" https://darksun.fandom.com/wiki/Mul
Since woman don't like manlet, such creatures can only exist in Athas, when the slave is forced to be get a child by a Dwarf and the woman almost always die https://forgottenrealms.fandom.com/wiki/Mul
You can't find it in 5e cuz 5e is baizuo shit, but they tends to have almost the same muscle density of Dwarves and almost the same statue of humans, ie - they are very powerful. A bellow average Mul would be on par with a ultra heavyweight fighter human. But they are away male and infertile.
if you can interbreed you are the same species, and elves in DA can interbreed with humans
Well, Grizzly bear and –polar bear can have a hybrid child despite being different species

About what I said about Blood Magic in Dragon Age origins in front of templars, you can only use consequence free cuz they removed reactivity from it >
And sadly, BioWare decided to replace this cool blood magic with the worst """necromancy"""" ever in inquisition and this shitstorm of a game would't be any different...
