So I decided to just jump right in making pokemon USA or North America (haven't decided yet on title). I am currently using Poke Essentials and RPG Maker XP to make this.
Currently I have created two whole maps. The Great Plains (Which will be the midwest) It's size is W: 75 H: 15.
I have also made a map called the Jersey Shore!!! It's a basic map of water and light brown (beach). This map is W: 20 H: 65.
I renamed my overlord map to The United States of America.
All of this was done from 8 AM-10:15 PM EST 2/21/2014.
