I first learned about these Sherlock Holmes games a few years ago & I've been hooked since. They scratch that itch for playing detective & this series is sort of a comfort food of gaming for me, the Baker Street theme makes me feel warm & cozy. With Devil's Daughter, Frogware shook up the formula to interesting results.
The most obvious change is the general world design. Holmes and Watson have both been redone, with new voice actors as well. Gone is the more traditional, stuffy Sherlock in exchange for a Sherlock that feels more like the modern artistic renditions of the Victorian hero. Watson has a hipster vibe & Holmes dresses more like the Cumberbatch version. Luckily, you can still change Holmes' clothes and he's got the suits seen in the past games to wear. Watson doesn't really play much of a role in this game, he accompanies you to a few places, but he isn't as ever present as in past titles. Baker Street and London also look a lot grittier, like they went through a Guy Ritchie filter, and you can't visit the Bookstore that's been a staple of the series. I also never remember hearing that Baker Street theme I enjoyed so much.

The next big change is the gameplay. The Sherlock games were never known for their action scenes, but Devil's Daughter tries to change your opinion on that. Be ready for lots of quick time events and balance beam mini-games. All of this new action doesn't take away from the solid mystery work either. Every case has a lot of sleuthing, puzzles and compiling clues involved, the last case not withstanding. And if you have trouble with puzzles, they give you a skip option, which I used at least once. Of all these games, this one does have the most AAA feeling to it. With the action mixed in, it feels more like it was made by the LA Noire team.
Like Crimes & Punishment, this game is rather short. There's only 5 total cases to crack and each one probably has an hour or two of content. They are all engaging, but I still wish they went all in and gave us a few more cases to play. Each one is self-contained and takes you to lots of neat locations to see different aspects of life in London. There is an overarching story about Sherlock's Daughter coming to visit. It's actually his adopted daughter, and we learn from Watson that Holmes was responsible for her father's death, but the rest is left in mystery. There's also a new lady who moves in next door who strikes Sherlock as an odd sorts. My guess was they were building up a love interest, I was wrong, very wrong.

The final case isn't a case, but a mission wrapping up this overarching story. It also adds in some sorta supernatural vibes which was odd when the rest of the game played it pretty straight. We learn who Holmes' adopted daughter's father really was, which after they revealed it, I realized I should've seen coming, but the twist got me.
All in all, I enjoyed this game. Some people said the added in action cheapened it, but I don't feel Frogware over did it, and they still have the solid detective game base they've perfected over 8 games. The fact this is game 8 may also show Frogware was getting a little tired with making Sherlock Holmes games and wanted to change it up, especially since Devil's Daughter is the last one we'll have for a while now that they're working on a Cthulhu game.
