A fun game, if you're into things like that.

So, if you ran a country, what would it be like? how would your flag look?

mine, super new so it's not quiet what I want yet but you can see the flag there.

I prefer a Libertarian/Republic society myself, tiny government, lots of freedom, a free market etc.
Gold and Silver as the only currency, stuff like that.
