While there are more complex and intriguing crime games out there and it isn't the longest game, The ABC Murders still offers good entertainment for the interested and serves as a decent port into the murder mystery puzzle genre. Some core mechanics need fine tuning, but the balance between the different game elements is generally good. The interrogation scenes as well as the deduction phases could be a bit more elaborate and slightly longer (because they are - hands down - the best bits of the game) but the overall flow of the game is pleasant.
[T]his is a very good game and it's definitely showing another side of the franchise that isn't just a tired, cloned cash-cow in a new dress.
Crimes & Punishments is one of the better, if not the best, Sherlock games out there, and if that's not saying much to you, it's also one of the better investigation-style games. The balance and variation of gameplay should be applauded. The developers are definitely onto something here.
If you're into puzzle games though, or if you're missing the good ol' days of Lemmings, you might like it as a substitute as it does cater to fans of both.
All-in-all, it's decent enough to pick up and play through a mission when you have a little bit of spare time, but not really something worth making the time for.
