There's a reason why the Ghost Trick fandom's motto is 'play Ghost Trick', and I agree with the sentiment. Shu Takumi uses his previous experience with the Ace Attorney series in order to create a stunning, complex narrative that spans much more than the simple murder of your player character, Sissel. The plot is far more quicker paced than Takumi's previous works, but the combination of a constant stream of information given by Ghost Trick's characters, the simple yet intriguing dropplings of the game's main mystery, and the jumping from one aspect of a mystery to another is enough to keep the player hooked in. Nearly every character in the game plays an important role in Ghost Trick, and while most characters lack the depth that Ace Attorney has, their quirkiness and ability to charm the player makes up for it.
And of course, the plot twists. Ghost Trick relies heavily on plot twists in order to create its unique story, and fortunately, every one of them hits the mark in that regard. I advise any new players reading this to avoid looking up anything related to Ghost Trick, as the game is best experienced without any prior knowledge of the game.
The puzzles deserve a mention too. While they're not as eye-catching as the story, they're a rather unique kind of puzzle, owing to Ghost Trick's central mechanic, and the way they promote experimentation and quick thinking is something to take note of. At times, they can be somewhat repetitive and irritating (the whole prison segment comes to mind), but it's a minor enough flaw that I can excuse it.
All in all, if you're interested in more of Shu Takumi's works, Ghost Trick is definitely something I recommend. It's very close to being a full 5 stars for me, but there are juuust enough flaws that I can't give it a 5 out of 5, in good conscience.
