Europe, south east Asia, the US and western Africa has a greater density of territories than the others. Why not divide the oversized ones like you did with the european countries?
It seems weird to name the northwest of Sweden to Central Sweden. The territory called Göteborg resembles the part of Sweden called Götaland. If you rename it to Götaland, consider using the [Lands of Sweden](
http://en.wikipedia.org/wiki/Lands_of_Sweden) as the territories, if you want to go for accuracy, that is. If not, consider just renaming Göteborg to Gothenburg as that is the proper name in english.
And btw, Gibraltar is a bit small.
