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.
