Well, blame all the politicing and arse-kissing that caused us to get amazing and fascinating Civilizations such as Canada and Australia.
Ironically, I actually like playing both Canada and Australia - but i'd rather not have them over an actually historical/historically relevant culture, such as hmm... the Assyrians, the Hittites, the Portugese, the Tlingit, the Haudenosaunee, the Tuscans, the Berbers, the Nepalese, the Filipino, the Flemish, the Cumans, the Tupi, the Estonians, The Isle of Wight, etc.
