And now a False Dichotomy. I will repeat what I told you earlier. It's a feature that is unique, which is better than nothing.
What are what? Lack of orcs makes it different than worlds with orcs, which at this point is every other setting that didn't come over from MtG.
I just asked you what made Dragonlance unique. You refused to answer, and instead just said "it lacks orcs."
Anyone can make a setting that lacks orcs.
I have, multiple times. My current setting lacks any and all goblinoids--in fact, really the only sapient races it has are the PHB races, minus dragonborn and plus bullywugs and kobolds, and a small number of monster races like fey, undead, and dragons. Does that make my world more unique than Krynn?
So
is there anything that makes Dragonlance unique? Or is it just "no orcs"?
And I can tell you this: if I had a sudden need to add a new sentient race to my world to accomodate a player...
I would.
It would be a lot harder than with three humans.
Not at all. It might even be easier, depending on the type of horror I want to go for, the type of players, and what sort of things they're OK with. Because (as an example) tempting them to resort to a more primal nature is
prime horror material, especially when only one of those three races is a predator. And I don't even need to resort to
that when all the standard horror plots are still available to me and would work whether or not the PCs have fur.
Funny how you're adamant you can run Discworld in D&D, despite how vastly different that setting is from the typical D&D setting, but think it would be too hard to run a horror game with non-human PCs.
I feel that you're just being a contrarian for the heck of it.
Add the race of martians to Earth as of 10,000 years ago and still living here today and Earth would be a very, very, VERY different setting than the one we live in.
Not according to some conspiracy theorists.
But orcs aren't Martians and Athas isn't Earth. Why would orcs be any different than any of the other big, buff, violent races that already exist on Athas?
Since you seemed to miss it in the quote of mine directly above this response, I'll put it here. I'm going to assume that you missed it rather than deliberately skipped it in order to twist my argument again.
"The setting won't fall apart, but it will feel different."
You keep making this claim. Prove it.
