Yes they are all fictional creations that draw on the same (real-world) mythology, so certain similar elements show up in them. No reason for the lazy "actually they are the same deities as the ones from Toril" slop that we've been subjected to.
Yes, all that happened on cultures that closely interacted on a single world. (And Krynn already has that - Paladine etc have different names and identities amongst difrferent cultures). But this is different planets we are talking about, where gods are real entities not just the syncretic...
No. And Thinking about "analogues" for what are fundamentally completely different deities is an element of Crawfordism-Perkinsism that I hope we leave behind.
Ironically it's actually a reason to eliminate most of the current playable species and reduce it to human, half-elf and half-orc. Players actually have no interest in getting into a non-human perspective, so let's not even bother pretending.
Great, so why have any specific species in the Player Handbook if you can just do that? I don't need an elf or dwarf species as a mechanical concept, I can just write "elf" on the sheet after all.
Come on, do you even see what you the objection is at all? Handwaving a loosey-goosey "you can...
Exactly, people aren't annoyed that a specific mechanical representation of half-elves and half-orcs were removed, they're annoyed that it was removed as a character concept entirely. "Just play an orc like any other orc"
Well if they actually planned these things they could go like Paizo. When Paizo stop using a D&D-ism they already have another term ready to go. But WoTC are by nature reactionary, not really forward-thinking. Half the time they don't even understand why they stop using a term beyond "the...
So weird, since posters here were saying half-orcs and half-elves still existed in FR, it was just that they would now be mechanically represented with the full-blooded ancestor's stats, but now it's all gone Damnatio memoriae.
They didn't leave twice. They stopped listening to prayers once (but were still there) and the second time Krynn was the thing that was removed. The gods stayed where they were.
I never understood the "Dark Sun is future Dragonlance" angle. There's literally no common touch points at all, the maps share nothing in common. Dark Sun has halflings as a big part of its setting, whereas Dragonlance bans them.
The only commonality seems to be no orcs.
