Hard to say when you're stretched out by 15+ characters, but I'd probably say Greed, Nike and Industrial Warfare. They have the most prominent voices in my head and they know what they want to say. None of this beating around the bush, thinking for hours kind of thing I have to go through with the others.
Greed's fun to play as the man that has everything but flawed beyond belief; Nike's just fun as a cool-leveled character; and Karl's writing, I love thinking about the most because of his attachment to the history of warfare, my fav topic in history. And the fact that they all have crazy siblings, of course ♥
