I don't find Florey to be a stranger choice than Sappho, Hildegard or Copernicus personally. I think there is some incongruence having both political leaders and non-ruling personages in the same bucket, but at the same time from what they've been saying in the developer diary videos, it sounds like they're interested in deconstructing preconceived notions/traditions of the genre. Whether or not they succeed at that remains to be seen of course, but I think it's at least a unique take to step outside the regular cast of characters to ask who is fit to represent a culture, and what it means to 'lead.' Florey in particular I think represents that for me - I'm struck by the quote on his Wiki page from PM Menzies saying that "In terms of world well-being, Florey was the most important man ever born in Australia."
