This review of "Assassin's Creed: Black Flag Resynced" uses the Ship of Theseus paradox to describe the game, which has been "rebuilt from the ground up" on a new engine. The reviewer notes that while there is clear love for the source material, the result is a mix of excellent new elements and awkward, aged ones. The 13-year-old game design, with its lengthy sailing sections and dated quest structure, feels its age next to new content. The combat overhaul is praised when it works, making Edward Kenway feel like a scrappy pirate, but is criticized for its buttery and awkward lock-on mechanic, which leads to frustrating fights. The review concludes that the game oscillates in quality, with the skeleton of an aging game crammed into newer, tidier skin, resulting in an experience that is sometimes excellent but often marred by its rough edges.
