Reference excerpt

Shin Megami Tensei IV is a role-playing video game developed and published by Atlus for the Nintendo 3DS. The game is the fourth mainline entry in the Shin Megami Tensei series, the central series of the Megami Tensei franchise, though no direct story connection exists to previous entries. It was released in May and July 2013 for Japan and North America respectively. It was released digitally in PAL territories (via Sega Europe) in October 2014. The gameplay is reminiscent of previous Shin Megami Tensei games, carrying over the turn-based Press Turn battle system, where players and enemies fight and exploit weaknesses, allowing either side to gain additional turns or lose them. The story focuses on Flynn, a samurai who protects the medieval Kingdom of Mikado from attacks by hostile demons. When a mysterious Black Samurai begins transforming the population into demons, Flynn and three companions are sent to capture her. The pursuit of the Black Samurai drags Flynn and his comrades into a startling revelation and a power struggle between angelic and demonic forces. Development began after the completion of Shin Megami Tensei: Strange Journey, with the team deciding to make a fourth numbered entry in the series based on fan requests. The team intended to evoke the style and feeling of the original Shin Megami Tensei. The main characters and some demons were designed by Masayuki Doi, previously known for his work on the Trauma Center series, changing from series veteran Kazuma Kaneko, whose series demon artwork is still featured alongside a host of guest artists' demon designs. It debuted to strong sales in Japan and was one of the better-selling games of the year. Reception of the game has been generally positive in both Japan and the West.

Gameplay

Shin Megami Tensei IV puts the player in control of the samurai Flynn. Navigation takes place both in the third-person perspective with 3D-rendered environments and a 3D overhead overworld map. On the overworld map, icons represent the player party and enemy demons. Battles take place from a first-person perspective, with the enemy visible on the upper screen and party status and commands on the lower screen. As with other role-playing video games, the character grows stronger and advances by completing quests; they also earn macca, an in-game currency to buy items and equipment. Some quests relate to the main story and are mandatory, while other quests are optional. Should the player be defeated, they can return to the game by spending macca (the in-game currency). Nintendo 3DS Play Coins can be used in place of macca. Repeatedly dying unlocks an easy mode: in this mode, the player can flee from battle if they choose. Enemies wander the environments Flynn explores. A battle starts when Flynn strikes an enemy (granting the player an advantage), an enemy runs into Flynn from the side or behind (granting the advantage to the enemy), or when they run into each other head-on. In battle, the player controls Flynn and three demons, with one AI-controlled human support character. During battle, both player and enemy actions are governed by the turn-based Press Turn System, a battle system carried over from previous entries in the Shin Megami Tensei series. The system revolves around exploiting physical or elemental weaknesses: if a character strikes another character's weak point or deals a critical hit, the party gains an extra turn, while if the attack is absorbed or blocked, they lose their turn. If a character strikes a weakness or gets a critical hit, there is a chance they will enter "Smirk" status: Smirking temporarily increases a character's damage, eliminates their elemental weaknesses, and gives them a high probability of dodging attacks. Other systems continuing from previous entries in the series are Demon Recruitment and Demon Fusion. To recruit demons, the player talks with a demon instead of fighting them, and must negotiate for their services: these negotiations can involve flattery, bribery, or threats. Demon Fusions allow the player to take two demons and fuse them into a new form, granting new abilities. During fusion, players can choose which skills are retained and which are discarded. The demon's fusion history is recorded for players to look over during the later stages of the game. Negotiation and Fusions also grant experience points for the player. Some demons change forms on their own without needing fusion; instead, they must be leveled up with experience in battle. As Flynn levels up, new fusions become available. Tamed demons teach new skills to Flynn. Using the Nintendo 3DS' StreetPass system, players can trade demons.

Synopsis

Setting and characters Shin Megami Tensei IV takes place in a world separate from the rest of the Shin Megami Tensei games, even though recurring demons and abilities are present. The two main locations are the Eastern Kingdom of Mikado, a feudal society inspired by Medieval Europe which is secretly controlled by angels; and Tokyo, a modern-era city enclosed in a rock dome and overrun by demons. Before the game's events, when Tokyo became a demon stronghold and was threatened with destruction by angels, a member of Tokyo's Counter-Demon Force tamed the God Masakado (マサカド), fusing with him to create the protective dome over Tokyo. Mikado is built on the dome's surface. After the dome is created, only twenty years pass in Tokyo while over a thousand years pass in the Kingdom of Mikado. Remnants of Tokyo's technology, studied by the Mikado church as "mystic relics", remain scattered throughout the land. Players control a Samurai who is the reincarnation of Tokyo's savior. His default name is Flynn (フリン, Furin): as with previous Megami Tensei player characters, he is a silent protagonist, with his actions and attitudes determined by the player. Three other characters accompany Flynn on his journey, representing the game's three main moral alignments. They are Jonathan (ヨナタン, Yonatan), representing "Law"; Walter (ワルター, Warutā), representing "Chaos"; and Isabeau (イザボー, Izabō), representing "Neutrality". Other important characters include Navarre (ナバール, Nabāru), a rookie Samurai; Burroughs (バロウズ, Barouzu), Flynn's AI assistant; Lilith (リリス, Ririsu), a powerful demon from Tokyo; and Issachar (イサカル, Isakaru), a former childhood friend of Flynn's.

Worked examples

Example 1 — a first encounter with Shin Megami Tensei IV

Start with the simplest possible case. Write down what Shin Megami Tensei IV claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Shin Megami Tensei IV before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Shin Megami Tensei IV ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Shin Megami Tensei IV

In research
Shin Megami Tensei IV appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Shin Megami Tensei IV in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Shin Megami Tensei IV is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2013 video games, Atlus games, Cyberpunk video games, so understanding it makes those chapters shorter.
In everyday life
Look for Shin Megami Tensei IV outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
