Ok, I'll tell you about my starting area and how I want to do it.
As you know, create a complete quality level is difficult. You need experience, a lot of time and a great desire. What if you do not have something like I?
I use a simple method that allows me to get what I want.
My task:
I need a beautiful wild mountain terrain with no trace of civilization. No buildings, no ruins, only a wild nature.
Moreover, I need a generated location so I need chunks.
My method is simple - open the needed chunks and change them. Remove all traces of civilization and, if necessary, replace them with something suitable (stones, rocks, trees).
It should look something like this:

Note that I did not remove "the events" and some "the lootables" - later I replaced them with my own.
Pay attention to The Bridge - it is a necessary part of this piece. I replaced this bridge on the rocks with an invisible floor.
For the beginning I plan to use 1-2 variant for my location:

In total I have 21 chunks. Each piece contains 2-5 variants as a result we have a huge amount of work(32-50 chunks for 1 variant)

, but it is much easier than creating it from scratch.

When I finish a replacement, I will get the necessary wilderness. Then begin the next stage - events, dungeons, lootables.
