Jack the Ripper’s story hasn’t been solved, which makes it prime fodder for such fictionalization. It’s the rare “based on a true story” tale that doesn’t have a predetermined ending. It is all of this backstory that makes Sherlock Holmes vs. Jack the Ripper such an interesting play experience. For an adventure game to work as an immersive experience, it has to draw the player into its world; for such an experience to be effective when so much of it is drawn from either real-life experience or a well-known body of fiction, attention to detail is paramount. Happily for adventure game fans, it seems Frogwares has done its homework. Given Holmes’ opposition, it should be well understood that the game’s not a laugh riot, but this is one of that rare breed of adventure games that simply doesn’t need humor to succeed—it simply begs to be played, and while as an adventure game its appeal ceases once it ends, it’s the type of game that will have you thinking about it long after you’ve finished it. Meaning this is the gift for the gamer on your list; just don’t plan on seeing them until New Year’s.
