HELP

I have never made a map before and have an idea for a cool scenario for a part of the world map is there a way to delete multiple countries like if I wanted to delete all of Africa is there a way
Could I use a map like the un as a template that would be the best
I may have overlooked the answer before asking this question but wanting help if there is anyone that can help please do I have looked through the help forums but wasn't to helpful

You can either delete each country one by one (not too much of an issue, delete the countries from the county list and delete the borders with the select border tool) or disable the countries you don't want in scenario editor (they'll have no cities but they'll still be passable, you need to make a no-go over them if you want them to be impassable)

Thanks i appreciate the help
