How realistic are world generators today?

I'm a big "Elder scrolls 2: daggerfall" fan and love the game world.

In this regard, the question came up to me whether there are better developed and almost realistic world generators today.

Of course it was obvious to google, but I only found mods for minecraft or 2d card generators.

The real question is: does anyone know such realistic world generator?

There will be no such thing in a few years.
In the MMORPG area, as far as I know, Black Desert Online and / or Astellia is the furthest in terms of graphics.
