Out of all the Blackwell games so far, this one is SIGNIFICANTLY longer. Fans of the story will love to hear that a lot of loose threads from previous Blackwell games start coming together in an awesome way in this installment. "Everything is connected" indeed! The conclusion to this one is rather unexpected and leaves you with that great feeling that the story you're partaking in is every bit as good as tv or film.
As much as I have to praise the great-as-usual story in this installment, I unfortunately have to dock this one a few points in the puzzles department. In the previous Blackwell games, the solutions to puzzles have always for the most part made perfect sense, and you could arrive at the solutions very logically. Deception is the first installment in the Blackwell series where I have felt that some of the solutions to the puzzles involve doing things that you are very unlikely to think of doing... or doing things that past experience has taught you would never work (e.g. what you can and cannot do with the neck tie) or involve factoring in a piece of information that has never mattered in a Blackwell game before and so it doesn't even register as something you should pay attention to (e.g. in ONE case and ONE case only, you need to notice what time of day it appears to be based on the sun in the sky when looking at the map menu... I mean, COME ON. It's a menu, and there is ZERO precedent for that and it never comes up again.)
Basically, some of the solutions in Deception rely not only on the information you've uncovered while investigating (as is usually the case in Blackwell) and instead throw in some some one-off, special case thing that adds a sort of secret hitch to uncovering the next lead. And actually, there is one puzzle in the game where you have to perform a set of actions in a particular sequence, but if you do it in the WRONG sequence on your first try, then the puzzle is completely unsolvable.... there IS a way to reset it by talking to a character at a completely different location, but you have no way of knowing that, so if it happens to you, it is extremely confusing.
Anyway, I don't want to harp on about it too long. Suffice to say, I thought the puzzles were a little more flawed than usual in this installment, but still an excellent game, and the story was as good as ever.
