DO NOT DOWNLOAD THIS! I am leaving it here as an archive of my previous work, but if you want to play the latest version of the mod then avoid this.
This download contains custom maps made by the community as well as the American (USA) civilization.
Note that custom maps are already downloaded by the mod's patcher, but I still added them to this download since they are all part of the "My Documents" content.
The reason for why the patcher doesn't download this is because it cannot skip the American home city files if you have them and made progress with the civ, which means that each time you would start the patcher all your progress with the American civ would be deleted and you would start from scratch.
The American civ files are present in the mod's installers though so that is another way to get them, but if you installed the mod by only running the patcher then you need to download and install this.
Please remember that I did not make the patcher and it was a gift from a player and now friend.
To install it copy the "My Games" folder from withing "usa_civ_&_maps" to your computer's "My Documents".
