Which Might and Magic universe are you referring to?

..........
So, it wasn't done just for show; the concepts are quite well-thought-out.

It was done just for show. They replaced units that harmoniously complemented each other with something completely random. Yes, they came up with a backstory for them; otherwise, it would be stupid to introduce them. But a backstory like "these are undead from those who died out/don't exist anymore" is just an excuse to avoid fully thinking through the design.

Ah yes, green-skinned orcs are a Blizzard thing, and they can be sued for it. But in the original Heroes universe, only goblins were green, and orcs were always brown, with the third one being an exception.

Orcs are the Professor's creation; green-skinned, brutal orcs are a creation of Games Workshop in the form of Warhammer. Blizzard stole the concept from GW. Just saying. And yes, "greenskin" exists in Warhammer, Dungeons & Dragons, Disciples, and many other games and universes. It's impossible to determine the appearance of the races based on a few parts of Heroes because it changes too much from part to part.

Furthermore, since the history of Askhan is unique, goblins, orcs, and others all have a common origin in terms of how they were created, not in terms of species – meaning they have the same mother (mages), but different fathers (demons, elves, beasts, etc.), which gives reason to consider them a race.

I don't understand you here. I'm not against considering goblins and orcs a race; where did I say that wasn't the case? And by the way, aren't goblins and orcs from demons?

Ah, yes, I remembered.
I read about the Might & Magic universe a while ago on Demilich's website.
It seemed kind of bleak and depressing to me. I couldn't get through it.
So, Askhan appeals to me more. Therefore, I think they are separate things.
In general, I think Askhan is cooler because, at least, he is interesting to me, while Xyn and others are not.

I couldn't get through Tolstoy's "War and Peace" in ninth grade, but I read Salvatore's "Dark Elf" cycle with pleasure. So, Tolstoy is crap; Salvatore rules! Morni, whether you agree or not, let's discuss it in the Warcraft thread in the off-topic section. I brought them up here as an example of breaking stereotypes, not for a flame war.
