I say yes because while I HATE the idea of Venice. I love the idea of outside the box Civs. And while I know very little about aboriginal culture, the simple act of survival they've accomplished is unparalleled. There culture has survived one of the harshes conditions on the planet, some of the earths most dangerous animals and climates, and a full fledged Super Power and empire. The fact that they circumvent our very European Idea of a civilization is a testament to their survival and is exactly why their people were marginalized in the first place.
I say Firaxis should turn Civ on its head with The Aborigines. Reward isolationism vs diplomacy. Reward Tradition vs Science.
Another Civ that's BEGGING for inclusion is The Swiss. NEUTRALITY and PEACE should be rewarded and for the swiss land trade Routes should be worth double or triple.
