OBJECTION!
Presentation:
Gyakuten Saiban 2 is a great game. It has awesome characters, great music, and great story. The way this game plays itself is in a somewhat visual novel gameplay. Even if you haven't played the first game, it won't take too long to pick up on events in the game, since it usually only makes vague references to the first game.
Story:
The game has 4 different chapter which have nothing to do with each other, and each chapter has nothing to do with each other, they are seperate cases. You play as a lawyer named Naruhodou Ryuuichi/ Phoenix Wright, as you defend clients and win the case. Each case is unpredictable and hard to crack, but each time you get your "Objection!" right, you'll get a pleased feeling.
Gameplay:
The game is viewed in a first person perspective. There are two stages to each case, Investigation and Trial. During Investigation, you go around talking to witnesses, Detectives, your partner and other people trying to find out information. Sometimes they might be hiding secrets which you unlock using a magic item called the Magatama. With the Magatama, you present evidence to the person you're talking to try unlock their "Psyche-Locks" which are hiding their secrets. Each time you present the wrong evidence, you lose some of your life bar. In Investigation, you also examine the crime scene and other related areas to find new clues related to the case. In the Trial stage, you put all your Investigation to good use and present what you have in court. You do this by cross-examinating witnesses, by finding contradictions by touching or yelling "Objection!" or pressing the witness with "Hold It!".
Music:
There's not much to say, all the music in the game is good. There are great suspensul tracks the play in court, saddening tracks, and quite cheerful tracks too. The music in this game is wonderful.
Overall:
If you enjoyed the last game, you know you're going to enjoy this game, and you're going to enjoy this game, there are still 3 games in the series after this to play. In Gyakuten Saiban 2, There's probably not anything bad about this game at all, other than the fact that people who hate reading or have trouble reading are going to have a tough time with this game. But, for the people who don't mind puzzle cracking and a load of interesting dialogue to read, I recommend this game to you. As I said before, the Story's great, the Gameplay's great and the Music's great. I give this game a 9 out of 10.
