Part 1: The story
Part 2: The Gameplay
Apollo Justice: Ace Attorney, but the major change is in Phoenix's magatama and the psyche lock breaking. It may not have mattered to many players, but I found it rather upsetting. They took off the penalty bar! For me, this kind of diminished the amount of challenge I had gotten from the old trilogy. But it didn't put a damper on it too much as the ability was used only two times anyways. (not counting the DLC case that I haven't played.)
Aside from Apollo's bracelet and Phoenix's magatama, the new lawyer Athena Cykes has brought something new to the table in the form of the Mood Matrix. Despite it's stupid name, the Mood Matrix proved to be quite challenging and fun to use. The basic concept is that using Athena's special hearing, you can compare the witnesses testimony to the sound of they're heart's true feelings. If a piece of the testimony contradicts an emotion, you need only point it out. But that's not the only new mechanic in the game. There's this new thing that's used around the climax of each trial called the Thought Route. It basically gets you inside the thinking process of Phoenix, Apollo, and Athena while they figure out what the contradictions means. In a way, it kind of reminded me of Edgeworth's logic from Ace Attorney Investigations in that you take pieces of information that's been acquired and put it all together to come up with a conclusion which ultimately turns the whole case on it's head, pretty exciting eh?
