Reaching the credits in Fire Emblem: Fortune's Weave should take approximately 45 to 50 hours, but seeing every story path can easily push a playthrough beyond 120 hours.
Later paths also become substantially faster because completed routes unlock powerful bonuses, while repeated Part 2 cutscenes can be skipped. That means four paths do not take four times as long as one.
The annoying answer is that it really does depend on how you play. Fortune's Weave is very malleable, letting you take a very direct route to the end, pick and choose which routes you go through, and alter how optimally you play all the while.
One Part 1 path, one Part 2 path, and then Part 3 immediately
These estimates naturally vary with difficulty, reading speed, optional quests, exploration, unit management and how often battles need to be restarted.
The shortest route to the credits takes around 45 to 50 hours.
To finish the game this way, you can complete:
A first Part 1 takes roughly 20 hours. Part 2 adds approximately seven to ten hours, depending on how directly you progress, while Part 3 contributes another 20 to 25 hours.
