Mountains like Civilization 6

Hey guys,

At the moment I create a little game which is graphically inspired by civilisation 6. Do you have any tips for me how I could model this type of mountains? Is there maybe a recommended addon or technique (displacement map.sculpting…)?
here is a picture how it should look like:


Thank you very much.

For the mountains themselves, the ANT landscape addon (default, so nothing to download) is probably your best bet. Texturing is a little more complicated, but there are many tutorials on this.
