This is supposed to pick a random AOE2 civ but baring in mind civs that you do not want to play (e.g Incas).
A list of all the AOE2 civs is in all_civs.txt and that is the base list of civs the python script chooses from. If you want to exclude a civ from being chosen, add it into banned_civs.txt.
all_civs.txt is correct as of the Indian Dynasty expansion and when the new Indian civs come out it will have to updated.
Don't know how well the script works but I ran it 450 times and I never got Incas :).
