Which Might and Magic universe are you referring to?

This simply indicates the English translation of the city's name. Inferno and Necropolis have such names because their translations "don't sound good" (Hell and City of the Dead). But for others, the English name "doesn't sound good." If they were translated like that, we would have all sorts of Heavens, Dungeons, etc.

There are no words like Dungeon or Heaven in Russian. But Sylvan exists. Although of foreign origin, it still exists. Don't believe me? Google it.

My question: What exactly do you like about the Original World "in general" and "compared to Ashan"?

The third game's campaign showed me all the charm of the original Universe. Perhaps I am doing something wrong by drawing conclusions based on only one part, but I can't help it – the impression is too strong and good. The plot has a sense of epic scale, which is lacking, for example, in the sixth game. If there is a demon invasion, go all out, create some incredible campaign with an exciting plot development so that the player can somehow feel the situation (especially since the graphics allow it)! But no. Everything is the same, following templates, without much imagination. I keep using the "Reign of Chaos" campaign as an example – it is magnificent. That's where creativity, a well-thought-out story, and engaging gameplay are. And that was in 2001!
The Original Universe is special. At least because it was created with soul; commerce was probably secondary for John. And that is noticeable. Of course, the Ancients bother me a little, but I understand that they are essential; they are the framework of that world, so I had to come to terms with it. When I play the fifth or sixth game, I have the feeling that everything was done just for the sake of it. Just to have it. The exception, as I said before, is the map "The Fury and the Mire" – I have an inexplicable love for it.
