I will not be too critical when you submit medieval or older states, as things were pretty complicated back then. I've decided after thinking that i will accept former colonies that are more or less recognised as a country and former nations if they have a name change, on the condition that it sounds good.
as drivers we will take persons that lived in that country during that era, it doesn't matter what his actual profession was. (i wil only accept an entry if you put forward both country and driver)
I however don't know how to make a mod, but i will make a topic anyway to get for an entry list and a race calender. Someone who can create the mod, you're welcome. I might try to do that myself, but that will take months, so have patience! In between keep submitting nations!
