I've been playing Cindered Shadows and pondering about the campaign while I do so. One thought that crossed my mind is how the campaign leads into only two real choices "For the Church" or "Against the Church". While this is probably more than enough for most people, I feel there could've been a lot of potential in a third choice where you fight both the church and Edelgard as you your newly formed faction would disagree with how the other two factions are playing out.
I know some discourse here would be "Well if you don't like the church you should be fine with Edelgard". But I don't think things are that simple, especially when her route is locked onto Black Eagles. I remember playing the Golden Deer route and going "yeah, i'll join you" in a dialog option and being told "I don't believe you". Even though I was 100% fine doing a 180 on my students. That's probably neither here nor there as the game is loaded with a lot of "fake" choices throughout, but it adds to why there being only 2 real options sort of hinders things.
Aside from all of that, i'm just a big sucker for multi-faction conflicts as it adds a lot more flavor to numerous elements. I know of course that other parts of the game would've needed to change, especially when it comes to the story. But the possibility of what could've been is really interesting to think about and while I love the Ashen Wolves and the game itself, sometimes I do wish we would've been treated more to a "Conquest" style expansion instead.
**Note: I'm a new Fire Emblem fan and have only played everything released after Awakening. So if prior games did this i'd like to know. Since that would be something i'd like to see remade.
