Another thing I would like to note:

If you have never worked with any game engines or are curious about game engines. I would love to show you hero engine. I can set you an account up right away and get you logged in to see what will be used to make the world you will basically have a large hand in designing! Heck if you want you could even put your world building skills to work if you liked

Either way don't be scared.. at the end of the day I just need some maps made... pretend I was doing a DnD campaign or something. No game dev knowledge is required on your part, and anything you need to know. I will tell you
