Unlike main Assassin's Creed installments, Jack the Ripper benefits tremendously from a streamlined approach. The add-on quickly ushers the player from mission to mission, with little dillydallying in between. Ubisoft couldn't resist the urge to pad the expansion with some trademark side events, but they're not pressing, not in-your-face, and ultimately not really important. It's just three hours of mostly quality main story content.
Jack the Ripper can't aspire to reach the heights that Syndicate did. But, it also doesn't suffer the same setbacks. In a game where open-world strain can become a serious problem, this add-on is a mostly-focused reprieve. Sure, there are some fumbling moments, but there are also some elegantly-handled ones. Given the difficult source material and the obvious danger of stumbling, Jack the Ripper mostly doesn't, and that feels like a best-case outcome.
