adding onto campiagn map

[Aemilianus the Younger]

Is it possible to add on to the map by making trhe map extend all the way east towards afghanistan and stuff like that.
and if that is possible, can i make that only happen after the Mongols arrive?\

probably really complicated

Yes it would be possible. You just have to draw up the map all the way (using some tool - best to check the tools/tut section).
You can also make it appear later. How to do this should be outlined in the campaign_script file as America is revealed when the world is round too.
