I finished Crimson Flower and Silver Snow recently and I'm almost done with Verdant Wind. I wish Crimson Flower was a bit longer, it had 1 loose end I wish it had covered. Silver Snow shouldn't have been a route at all, since it's almost identical to Verdant Wind, with the latter adding more to the story. The main downside of Verdant Wind in my opinion is that >! Claude's tactical genius isn't really shown, as his decisions are the same as in Silver Snow. The story does a much better job at showing Edelgard's and Hubert's tactical genius in the Crimson Flower route.!< I haven't played Blue Lions yet, but I want to finish it before the DLC comes out. I think it's safe to say that the story consists of every route except for Silver Snow.
