Oh, Great another person who thinks only they understand this is a fantasy game and thinks the rules of the world don't matter....
Hardly. It isn't that I think only I understand a thing, nor that I think the rules of the world don't matter.
I think the rules of our real world
don't matter to the game world, is all.
Let me guess your a story GM how hand waves inventory management?
I don't worry about inventory management when the PCs are flush with cash, and are in a place where resupply is easy. If there is no difficulty getting the inventory, managing it is not interesting, and wastes valuable time at the table. My players would rather be in an exciting fight or tense negotiation or virtually anything other than counting exactly how many iron rations they have.
But, do be careful - this discussion is about the ideas, not us as people. Slapping a label on me to dismiss my point is weak, ad hominem
rhetoric. It doesn't stand up well.
Look, I am not saying your wrong but forget genetics (Not once did I mention genetics, so your the only one talking about that)
The idea that one species needs to be an "offshoot" of another to interbreed comes from the real world and our genetics.
you don't expect a human to sleep with a horse and create a Centaur.
Um... Greek mythology says otherwise?
There's a couple of competing stories about the origin of centaurs. In one, Centaurus was a man (with perhaps some godly blood in there somewhere, depending on the version of the story) who mates with the Magnesian mares. So, yes, a human sleeps with horses and begets centaurs.
Alternately, the centaurs come from King Ixion seducing... a cloud. Ixion had been trying to seduce Hera, and so Zeus made a cloud look like Hera. Ixion got busy with the cloud, and they birthed Centaurus, the first centaur. This hardly makes more sense than the prior version, biologically speaking. How more centaurs happen... is kinda foggy in this version. But they happen somehow.
Oh, and the Minotaur comes from the wife of Minos, mating with a white bull.
And, to top it off, Medusa, a human cursed by the gods to have snakes for hair, upon her death gives birth to... a giant, and a winged horse. 'Cause that makes sense, too!
If that happens one time and never before or again it makes since their is an in world reason for it.
If it happens once, and never again... you don't get a population. You get an individual. The Minotaur doesn't become a race of minotaurs, because there's only one of him, and he finds it really hard to get a date.
But, in any event, mythologies often have the various races that appear have origins with the gods of the pantheon and what amounts to the various magical spirits of the world. We don't need
Elves, humans, and orcs don't have to be "offshoots" of each other to interbreed. The idea that breeding comes from "offshoots" falls apart when dragon, celestial, and infernal blood get into the mix. There's no reason to think that dragons are offshoots of humans, or vice-versa, but we get dragon ancestry as a reason for magical power among humans.
The same is true with all the other races. I am not saying the should follow genetics but that they should have a consistent world.
Mostly consistent. I mean... magic, you know.
They introduce that some races can hybridize so they should state why, when, and which ones.
Generally, when, and which ones, sure. Why? Not so much. Not everything needs to be explained. It only needs to have a "why" if that is going to be a plot-relevant issue in the campaign that the PCs can interact with. I don't need to know if dragons and dragonborne are actually related unless a dragonborne PC is in line to be Queen of Dragons, or something.
Nothing about that requires real-world genetics and your condescending implication that this is a pointless exercise...
For a pointless exercise... you're putting a lot of effort into it. Next time, I suggest you ignore things that you find pointless, rather than get up in arms of them.
is a meaningless post attacking people
Dude. I didn't attack anyone. I made no statement about any real person at all. So, the tirade here... not really called for.
Please tone it down a bit. And definitely don't react like this to other posters. I can put up with this, but if you get in the face of regular posters, I won't really be able to let it pass.
