Fantastically involving (without spoilers)

First: I've played the game in English, therefore give my vote to the English voice actors from

If you want to play the game in English, you must set the DS settings to "English" only before loading them into the DS. The game contains both the German and the English version, and decides by the DS settings which will be recalled.

In order to assess:
I am primarily an Ace Attorney fan, and have played only 2 Laytonspiele, so I can say more about the AA member.
In general, it surprised me how well mixed the different styles of Ace Attorney and Layton and were connected to each other. You did not feel that a "break in style" exists - it has fitted beautifully.

The Voices
As I said, I have the English version of the game, including English voice actors - who have made their job wonderfully! Especially Maya stands out positively, while I imagined Nick's voice a little deeper.

Gameplay
The game combines the two different gameplays wonderful. To play both Layton and Phoenix over prolonged periods. While you walk around outside, you stumble as usual sorts puzzles available to solve. As far as I can see it, the Layton game is identical to the previous games.
In Phoenix Wright There is one new feature: While the usual trials can now interrogate several witnesses at once. During says a witness, the others listen and react may it - then we must dig deeper. On the whole a wonderful add-on to previous games.

For the actual story, I will not say anything, except that they are wonderfully designed. Especially for me as a AA-fan several allusions contained in the other games; I can not judge whether the same is true for Layton.

After this game, I am more disappointed by the last Ace Attorney game Dual Destinies; this shows here how to do it perfectly and the cut scenes not dramatized, but only to promote the story uses.
It's the perfect mix for fans of both series, and I hope that one day there a second part!
Absolute buy recommendation!
