Please don't take my stars personally. The Great Ace Attorney: Adventures is the first half of Ryunosuke Naruhodo's story and, for certain reasons, one of the most interesting games in the series. A few years ago, Shu Takumi left the numbered installments in favour of Ace Attorney: Investigations team to go their own way, while he was interested in telling a story about the past in a spin-off duology originally for Nintendo 3DS. I think the crossover with Professor Layton was a success in Shu Takumi's narrative vision, although he already showed his wonderful storytelling skills with Ghost Trick. YT user @bowloflentils made an essay video about it.
As I said, The Great Ace Attorney: Adventures is the beginning of Ryunosuke Naruhodo's journey, but... In a different way than his great-grandson. He's the defendant in the first case, and he's not even the protagonist of this story, but things happen on a transatlantic ship to London, and Ryunosuke has to take the spotlight from his senior: Kazuma Asogi. With his assistant, Susato Mikotoba, Ryunosuke will have to face the modern British justice system in the face of the outdated and narrow-minded Japanese system. I think it's Japan, but I didn't see a hamburger stand, so...
The story follows Ryunosuke through the many problems he has to deal with on his arrival in London: a murder case on his first day, a bizarre fatal accident involving one of Japan's greatest writers, Natsume Soseki, on his second day, and a final case where everything comes together. It's not a grand story, but it's the most fitting to show the development of Ryunosuke's character as a lawyer. In that sense, I can't give the game a higher rating, because it's an unfinished story, but it's necessary for the sequel, and it's really well-written. I also appreciate the fact that the game leaves some mysteries unresolved and doesn't conclude the story with a typical 'anime cliffhanger".
In terms of gameplay, the cross-examination is more refined and the trials take on the mechanics of the crossover with Professor Layton. These additions enrich the overall dynamic, and the gestures and movements of the characters themselves are really fascinating. Some even have their own individual music themes. The game doesn't feel dull or overstretched.
P.D. I love the name change to Herlock Sholmes in the English version. It fits his character better.
