I feel like emotionally the story for Birthright was more compelling, but I do like Conquest cast more overall. I don't want to give a favorite route verdict until I finish Revelations, though. Also, there are certain points in each route that I think one did better than the other but I won't go into too much detail because spoilers. Though, probably the reason I was so floored by birthrights last few chapters is because I played Conquest first My friend who did Birthright first has a greatly different opinion on the Nohrian brothers than I do that's for sure.
Okay I'll go finish my hw now...
