Played through and finished this case today. Overall, I quite liked it! It was a very fun case for sure.
I liked how it was essentially 4-5 and how it actually justified Zak's actions in 4-1, something I never thought would be possible. It was well written too and the contradictions were clever enough. There were some typos scattered here and there, though, and I do think that the end dragged on a lot. There were some other flaws here and there, but this was really great to play through nevertheless!

Yeah, when you are done with Phoenix's testimony, story-to-gameplay ratio becomes progressively more and more unbalanced in favor of the story. But the purpose of this case was to wrap up all the abandoned AJ plot-lines and unanswered questions, properly tie the game to DD and SoJ, explain Phoenix's personality change between AJ and DD, and fix Trucy and Kristoph, which I've found lacking despite their potential as characters.

As for typos, english isn't my first language. And my proofreader quit pretty much after Edgeworth's opening statement ;P

But anyway, glad you liked it.
