Political map Xp [Request]

[Jakonen]

Ok, in the game im making currently im 20 mins in the game and need a exposition part where they are now and a short history lesson spaning 200 years.
I was wondering how i would make a world map with political boundries that highlighted when the character talked about it. I figure somthing to do with Show Picture and more than one map with each country highlighted.
if you have any tips or better yet a tutorial that could help, can you please direct me to it.

Nothing specific, but a long time ago when I was trying to achieve this effect I made four pictures - one of the entire map with all three countries just as it would be normally and one of each country separate and in a different colour, then I used the Show Picture Command, Label 1 for the base and Labels 2, 3, 4 for the others. Also, when I imported the country pictures, I set the semi transparent colour to the colour that filled in the country.
