I mean, come on guys, the division of factions into generic Good and Evil is just derivative and lazy. Every "Evil Empire" in history has had some semi-believable justification (for them) for world domination.
So, the entire set of Empires in this game that destroy the land for no tangible benefit just doesn't fly for me, and I suspect many other people. Even the Nazis had a psuedo-scientific philosophy as to why they were right and other governments were wrong, even if they were extremely misguided. (As they were obviously, as my wonderful Jewish girlfriend is proof).
Having one half of the factions in the game as completely unsypathetic does not help me enjoy the game at all. I'll admit that there is a notion of social Darwinsim for the Empires that is cursory and undeveloped and possibly has potential, but please please develop this further for FE. It takes minimal work, and adds to the ambience of the game.
Seriously, generic Good vs. Evil is for children. Let's have a a mature concept of competing world views for the next go-round.
