It's been said before, but I really think Juna should have been made the main character for 3 and 4, and not just because Rean is about as exciting as plain oatmeal. She has the most compelling circumstances- after seeing her once-independent country being annexed into the empire, she has to endure leaving it behind for the very nation that conquered it, and being a pupil of the most famous soldier that took part in the occupation. It has great potential! But because this series has Social Links and you choose which girl you love at the end, we have to be stuck with a male protagonist.
I was sort of disappointed by how little discussion there is of class politics here. When I played the first game it was the most interesting part of the story to me. But it starts to fade in relevance in 3 and then in 4 those issues are basically nowhere. It retrospect, it's clear that the tensions between the Noble Houses and the Reformist factions in the first game exist not because it has a point to make about classism but because it needs a circumstance to justify a civil war of the second game, which in turn sets up The Great Twilight, Rivalries, and all that jazz. The problem was that I was far more interested in seeing how Erebonia's class politics worked than learning about ancient curses or the history of the Gnomes.
Claire and Lechter got off easy and should have been in prison right alongside Rufus, or at least removed from any kind of position of power. No, I absolutely do not want them helping rebuild the empire in the aftermath, they helped cause this mess.
