How long it takes to finish Black Flag Resynced varies depending on how you play. If you rush through only the main story, it might take around 25 hours, especially if you’re playing on easy difficulty and skip side activities. For those who want to explore everything, including side quests, collectibles, and upgrades, it could take up to 50 hours or more.
Based on my experience and feedback from other players, a typical playthrough usually lasts around 35 hours, covering most of what the game has to offer before finishing Edward’s story. If you aim for full completion, such as unlocking all upgrades, completing all side missions, and hunting for treasures, expect to spend roughly 50 to 60 hours.
If you’re mainly interested in Edward Kenway’s pirate adventures in the Caribbean and skip the modern-day sections, you’ll probably spend about 25 hours going through the story. This streamlined version is easier to complete quickly, especially on lower difficulty levels.
Overall, the game offers plenty of content, from demolishing forts and upgrading ships to finding hidden treasures. Achieving the highest rank with legendary ships requires having all the best ship upgrades on the Jackdaw.
