From what I've seen so far, I think I will love this serie(hopefully there wil be more coming) more than Ace Attorney.
Phoenix Write2 was fine, but the last episode was really a bit too long for my taste , and too many spin offs, that I actually lost track of reality,plus the cartoon style can appeal for a little while, but then I get tired of the childish jokes, but I loved it never the less.
Hotel dusk seem to be much more of an adult affair, you can tell it's been build up from ground with the DS in mind( unlike PW) and you can tell the game has a much bigger scope.
And the way the two screens are put to use, along with the size of the characters, makes me feel I am playing with one big screen spread over two windows....it really feels different and more beautiful.
I think I will never get tired of games like this, and you can only have this kind of experience on the NDS, such a game will never look right on any other platform, and should be considered as a kill application that sells you the system, especially if there will be more of this kind coming up.
