Land = Life

Country forming = Age

Population = Knowledge

Flag = Looks

Stereotypes = Personality (Usually)

Reasoning

A country needs land to well, be a country so if they have land, they are a country so life!

When the country formed is usually there age, though I like to say there about 18 when they start as a country, but yeah.

The more people you have, the more likely someone knows something the next didn't, so more people equals more knowledge and stuff.

The flag design puts a impact on there looks, eyecolor, colors they wear, accesories that look nice etc.

Stereotypes usually have a impact on personality. Ex:Canadians are nice, canada is nice. But not always.
