Una de las obras más populares y aclamadas del célebre escritor Kotaro Uchikoshi, Nine Hours, Nine Persons, Nine Doors –también conocida como 999– es el tercer videojuego que he jugado en el que él participa como escritor, siendo los 2 anteriores Ever17: The Out of Infinity y Remember11: The Age of Infinity, 2 de mis obras favoritas de la ficción, lo que hacía que mis expectativas sobre 999 fueran altas, aunque sin llegar a esperar una experiencia que superara lo vivido en dichos juegos. Si bien, tras completarlo, 999 no me cautivó al mismo nivel que Ever17 y Remember11, es su narrativa la que lo hace destacar entre bastantes novelas visuales convencionales, pese a compartir muchos elementos con trabajos anteriores de Uchikoshi. En esta reseña mi intención es profundizar en las características que hacen de 999 una experiencia única. Cabe mencionar que me centraré solo en la versión para Nintendo DS, ya que es la que jugué y la que muestra todo aquello que me enamoró de la narración de 999, por lo que ignoraré la remasterización lanzada para plataformas modernas.

En la historia del juego, acompañamos a nuestro protagonista, Junpei, en su intento por escapar de lo que parece ser un barco donde fue secuestrado junto a 8 personas más, viéndose forzado a participar en un juego mortal conocido como juego nonario, en el que deberá resolver puzzles con sus compañeros hasta encontrar una puerta marcada con el número 9 que lo conduzca a una salida, antes de que el barco se hunda en 9 horas. Cada participante posee un brazalete que muestra un número único del 1 al 9; este brazalete sirve tanto para identificarse ante un detector ubicado junto a unas puertas señaladas con números del 1 al 9, como para activar una bomba implantada en el estómago de cada uno, la cual explotará en quien incumpla las reglas. Para avanzar, resulta necesario descubrir el número nonario correspondiente a cada puerta, que admiten el ingreso de entre 3 y 5 personas; de este modo, nuestras decisiones nos llevarán por rutas distintas, conociendo a nuestros compañeros poco a poco a través de charlas e interacciones durante la historia y la resolución de puzzles. Quienes hayan jugado Ever17 y Remember11 notarán que se trata de otra trama en la que Uchikoshi coloca a varios personajes en una situación extrema, en la que deben colaborar entre ellos para sobrevivir; pero, como decía, es su narrativa la que distingue a 999 de esas 2 obras, por lo que procederé a detallar más en dicho aspecto.

Primero que todo, quiero destacar algo que me encantó desde el principio: cómo usa las 2 pantallas de la Nintendo DS para contar la historia. En la pantalla de arriba vemos a los personajes y sus diálogos, mientras que en la de abajo hay una narración omnisciente que nos da detalles clave, como el contexto de la trama, los pensamientos de los personajes o descripciones de todo tipo. Dependiendo de lo que pase, la historia se narra de una manera u otra, incluso mostrando imágenes diferentes en cada pantalla para que entendamos mejor la situación. Estas 2 perspectivas distintas de narrar no solo ofrecen una visión más completa de todo lo que sucede en la trama, sino que son una forma súper ingeniosa de sacarle provecho a las 2 pantallas de la consola, diferenciándose así de las novelas visuales convencionales que suelen usar un solo estilo de narración.

Otro punto a destacar es la resolución de puzzles, que aprovecha al máximo la pantalla táctil de la Nintendo DS. Podemos investigar cada rincón de los escenarios tocando la pantalla para encontrar algo inusual o útil que nos ayude a hallar una salida, así como examinar los objetos que recolectamos, pudiendo incluso combinarlos en ciertas ocasiones. Muchos de estos puzzles son retos numéricos, en su mayoría ligados al número 9, por lo que el juego incluye una calculadora integrada para facilitar las cosas, aunque a menudo tenemos que tomar notas y analizar los datos con cuidado para resolverlos de forma óptima. Esto, en mi opinión, aumenta la inmersión, debido a que nos hace actuar de manera similar a como lo harían los personajes, usando la pantalla táctil en ciertos momentos para mover objetos a posiciones específicas o realizar otras acciones. Pero lo más destacable de los puzzles son las interacciones con nuestros compañeros de turno, que revelan detalles fascinantes: desde curiosidades triviales, como sus gustos, que ayudan a caracterizarlos mejor y a que les tomemos cariño, hasta aspectos más personales, como su pasado o sus relaciones con otros personajes. Estas interacciones no solo enriquecen la narrativa, sino que son clave para resolver los acertijos, ya que nuestros compañeros nos dan pistas o incluso realizan acciones que nosotros no podríamos hacer solos.

Hablando más sobre la historia, como mencioné, tus elecciones determinan con qué personajes pasas más tiempo, lo que lleva a que cada ruta ofrezca una experiencia única según tus decisiones. Esto puede ser una espada de doble filo: personajes como Clover tienen una presencia constante en casi todas las rutas, mientras que otros, como Snake, apenas aparecen, lo que genera una gran variación en su participación. Algunos personajes, al tener pocas apariciones, puede que no llegues a conectar con ellos tanto como quisieras, pero aquellos con mayor presencia son tan geniales que dan ganas de verlos más. La excepción es June, la amiga de la infancia de Junpei, cuya presencia destacada en todas las rutas te motiva a jugar cada una para desentrañar los misterios que la rodean y que envuelven el juego nonario en general. Estos misterios se intensifican con cada final normal, los cuales son finales malos, dejando al jugador con más preguntas y avivando la curiosidad por descubrir los secretos de este juego mortal. La obra construye una tensión increíble a través de sus eventos y misterios, siendo su mayor fortaleza.

Eso sí, como puntos negativos, tengo que decir que resulta molesto que no haya una forma más eficaz de saltar los diálogos ya leídos, pues debes mantener pulsado un botón hasta llegar a los nuevos, lo cual resulta fastidioso porque tienes que hacerlo en cada ruta. Además, no existe una opción para omitir los puzzles ya resueltos en rutas previas o avanzar directo a partes con nueva información relevante para la historia, así que toca siempre repetirlos. Pese a estos defectos, si buscas una trama con un misterio envolvente, llena de temas interesantes como dilemas morales o conspiraciones, un elenco de personajes variado y carismático, y un misterio bien llevado que te mantendrá intrigado mientras juegas, que aprovecha al máximo la Nintendo DS, 999 es un título que recomiendo en su totalidad. Como dije al inicio, aunque no me cautivó tanto como Ever17 o Remember11, se sostiene como una obra excepcional por derecho propio, con una narrativa única que destaca por su ejecución magistral, algo que las otras no logran de la misma manera. Si no lo has jugado, dale una oportunidad; y si ya lo jugaste, te invito a revisarlo para apreciar sus cualidades propias que lo hacen brillar.

I had this recommended to me after playing and enjoying the AI games. It’s striking how much it feels like those games exist in a common lineage to this one, down to mostly having the same strengths and weaknesses.

The main draw is the storytelling rather than the puzzles, which are rarely challenging. Characters and world-building are fine; I’d be intrigued by a more grounded story with the same premise but I get that that’s not what they’re going for here. It builds atmosphere effectively despite being an older game and I did find myself absorbed by the central mystery. The branching story is good but the way you’re forced to jump back and forth to get an ending that explains anything is a little jarring, although it’s mitigated by the fact that the game is not too sprawling.

I’m not anything close to an expert in the field of Japanese visual novels but my experience is that a lot of them are bogged down by an excess of text and repetition. This game is not excepted. Yes it’s a text-heavy genre by its nature, but that doesn’t mean the script can’t be made more agile and efficient.

Ah, look, a visual novel with an anime aesthetic. You probably know what this game is like.

I assure you, you do not. That's all I want to say.

Play it.

The plot-twists are indeed surprising and it adds up to the narrative that the way it unfolds makes it necessary for this story to be told through a videogame. Negative points are that the puzzles are way too easy and the story overall although interesting feel somewhat far-fetched. Anyway, it's definetely an experience I'd recommend to anyone out there that loves games (even if they don't appreciate Visual Novels or Escape Games).

Playing this umpteen times just annoyed me along with keeping up with the new information I learn behind each door was a drag. There still a few plot holes that I gave up trying to figure it out. I will not be playing the rest of the trilogy. but it was a nice looking game and has age well. The writing not so much.

2.5 star disappointing for a cult classic

J'ai joué d'abord à la version DS avant de jouer à la version PC du bundle "Nonary Games".

Ce premier opus de la saga Zero Escape gagnerait à être beaucoup plus connu ! Je n'ai jamais été exposée à une oeuvre qui joue aussi bien avec les concepts de diégèse et d'extradiégèse.

L'histoire aux accents de Battle Royale joue avec la réalité et la fiction, nous faisant sans arrêt nous arrêter dans notre aventure pour penser "et si c'était vrai ?". Ce n'est même plus de la suspension d'incrédulité, c'est une délicieuse paranoïa qui nous transporte et nous fait relativiser tout ce que nous savons...ou pensons être la réalité. Attention, un tel discours métaphysique, entièrement en anglais comme le jeu n'a pas été traduit, peut vite être rébarbatif. Mais si on aime les jeux bavards, on ne peut qu'être happés par la richesse du scénario.

Si le jeu ne se joue pas en temps réel (ayant du contenu pour durer bien plus que 9h !) et que le timer ne nous met jamais réellement en danger, les musiques aux accents industriels arrivent à faire monter en nous le stress essentiel pour être en empathie avec ces personnages forcés de concourir dans ce redoutable jeu de la mort.

Les personnages arrivent tous à posséder une personnalité propre, même Junpei, archétype du héro normal, se retrouve attachant dans ses réactions de jeune adulte paumé dans un complot qui le dépasse. Ces personnages sont servis par une direction artistique façon anime au poil, même si on regrettera quelques facilités un poil sexistes (coucou Personnage féminin à gros seins très animés, très peu vêtue mais superbement intelligente ! Bonjour Loli en uniforme scolaire !). Cette superbe galerie de personnages évolue dans des environnements en 3D qui ont été réalisés avec beaucoup de soin (on le remarque sur leur portage PC) pour de la DS et qui ont moins vieilli qu'on pourrait le croire. Mention spéciale aux décors très titanic que sont les cabines de première classe et la cage d'escalier.

Les énigmes sont variées et dans l'ensemble logique même si certaines énigmes appelant au cryptage peuvent être difficile d'accès. Dans l'ensemble on s'amuse bien sans trop de temps morts. C'est là que le bât blesse dans cette première édition DS:

En gros pour avoir la vraie fin du jeu, vous étiez amené à rejouer encore. Et encore. Et encore. Je peux vous assurer qu'après avoir fait les énigmes de la première cabine 5 fois vous en deveniez chèvre. Juste pour ça, l'ajout d'un arbre narratif "flowchart" dans le portage PC / playstation vita fait que je ne peux que recommander de découvrir le jeu sur l'une de ces plateformes au risque d'être dégouté du titre...

En tout cas, pour vu que vous parliez bien anglais, 999 vous propose une plongée haletante dans un thriller de science fiction comme le jeu vidéo n'en a jamais connu ! Un incontournable pour les aficionado de jeux narratifs.

I rarely play visual novels, but this one looked promising. I really enjoyed the opening here: it's a story about group of people who are trapped on some ship and they need to find an exit together, otherwise they will die.

In the beginning story and dialogues catched me and I was looking forward what would happen next. This game has several endings and you need to replay certain parts of the game to open all of them. In the end, you need to unlock every one of them to see a "true ending". It was interesting to see different finals, but the process of replaying was a little annoying.

Unfortunately, the "true ending" was a dissapointment to me. There were so many ridiculous mystic stuff, so it was hard to treat the story seriously. Characters had a lot of unnecessary long dialogues, and it looked especially absurdly when they were in a hurry. Of course, there is a cliff hanger in the end and there are two more games in this series (which are twice as long as this one), don't appreciate it.

I haven't played a plethora of visual novels, so forgive me if I come off as overly optimistic. 999 is about a group of people trapped on a sinking sink by an individual referred as Zero with their only way to escape is to play the Nonary Game. You play as the protagonist Junpei, a college student who doesn't know why he was abducted, where you must work separately and with others to solve the puzzles in each of the rooms designed by Zero in order to survive. You meet eight other individuals, all with varying personalities and pasts that will either hinder or enable you to survive. I don't want to go into too much detail to avoid spoilers and to avoid repeating information that you will learn/read as you play the game. Overall, your goal while playing this game beyond getting to the survival end (or, if you're like me, try to get all the endings...) is to get to know each of the people you're trapped with and more about their pasts; this is where the true story starts coming together.

This game is the first of the three game series Zero Escape, with the second one released as "Zero Escape: Virtue's Last Reward" in 2012 and the third one "Zero Time Dilemma" due to be released this year (2016), all published by Spike Chunsoft (Japan) and Aksys Games (North America). It's a text-based (visual novel) adventure game where you must select the correct responses to continue the story towards the ending you desire as well as solve the puzzles in every room you're trapped in. The puzzles ranged from fairly simple (sliding pieces of a picture together) and more challenging (doing a Sudoku puzzle [I don't think this is hard, just time consuming]). From what I hear, the puzzles in "Virtue's Last Reward" are much harder, so... yeah.

The story: It's a bit muddled and some of the facts didn't quite line up, but I found it interesting to start putting together everyone's past to connect all the pieces. Personally, I would recommend getting all the bad endings first, because there are small details revealed that don't make it to the true ending OR they provide another viewpoint. While I don't want to say without spoiling the story, all I will say is the story with Ice-9 was where I blanked out. It was almost... unnecessary.

The characters: Diverse, weird, interesting. Admittedly, I found June/Akane annoying at times because she was just so... frail. Ugh, I'm sorry, I hate wimpy, frail female characters. Of course, as you play Junpei, you're just constantly jumping down other people's throat for June/Akane's sake and it was just... dude, I get it! You have this obsessive, multi-year crush that no other girl ever managed to sway you! I GET IT! And don't get me started on their elementary school days...

The puzzles: I found them fun! I really enjoy the Professor Layton series, so it was nice to solve puzzle of a similar concept. I also really like exploring (when I play Pokemon, I check everything, every person, every building... I MUST KNOW IF THERE'S SOMETHING THERE) the rooms. Since you're on a ship with people of varying knowledge and intelligence, you learn some really weird facts and strange stories that will often tie back to your puzzles. This may annoy or interest people.

Overall: I would recommend for those looking for a casual play, who enjoy brain teasers and weird trivia at times. If you're looking for a story to put together and get to know characters, this would be of interest to you. If you want action, probably not so much. The game is rated M, primarily for violence (most described... in details) and dark themes.

There are three major elements of a visual novel that need to work simultaneously to make it a success, and I think that this game gets all three of them right. The story, first of all, is a compelling and twisting narrative that had me up all night finishing because I was too invested in the plot to sleep. The characters are amazing, all having their own twists and back stories that will have you either loathing them or loving them. Although the game is dark and contains mild horror elements (that I love) it has a sense of humour that lightens it up at parts. The story really is incredible. It is much better than any other visual novel I've played and the pacing isn't as unbearably slow as they usually are. As for other elements, the sound and the visuals are fantastic. Because 999 was inspired by 'the night of the sickle weasel', a sound novel, it really knows how to add sound into a moment to make it more suspenseful. And the music really is great, very atmospheric. The visuals are very warm and not too ridiculous as some anime styled art can be, with stylised character models and excellent colours. As for the actual gameplay - it's not that great, but that definitely isn't the reason to play 999. I think the puzzles are interesting, at least the first time around, but mostly they act as a sort of 'break' in the story that works very well. I could not recommend this game more.

I enjoy the concept of interactive fiction, but 999 was just so poorly written that I couldn't complete it. It reads like a 15 year old's anime fan fiction, complete with chatty, unnecessary dialogue, and characters so impossible to relate to and weak that you wonder how anyone could possibly give a damn about them. I didn't enjoy the puzzle style, either. Toss in the fact that you have to complete the game 9,437,710 times to get the "true" ending and you get 2/5 stars. It gets two because the game functions properly, and clearly wanted to go somewhere, but did not execute well enough to reach its intended destination.
