Dialog Tree
A dialogue tree, or conversation tree, is a gameplay mechanic that is used throughout many adventure games (including action-adventure games) and role-playing video games. When interacting with a non-player character, the player is given a choice of what to say and makes subsequent choices until the conversation ends. Certain video game genres, such as visual novels and dating sims, revolve almost entirely around these character interactions and branching dialogues. History The concept of the dialogue tree has existed long before the advent of video games. The earliest known dialogue tree is described in "The Garden of Forking Paths," a 1941 short story by Jorge Luis Borges, in which the combination book of Ts'ui Pên allows all major outcomes from an event branch into their own chapters. Much like the game counterparts this story reconvenes as it progresses (as possible outcomes would approach n where n is the number of options at each fork and m is the depth of the tree). Th ...

Dialog Tree Example
Dialog is an online information service owned by ProQuest, who acquired it from Thomson Reuters in mid-2008. Dialog was one of the predecessors of the World Wide Web as a provider of information, though not in form. The earliest form of the Dialog system was completed in 1966 in Lockheed Martin under the direction of Roger K. Summit. According to its literature, it was "the world's first online information retrieval system to be used globally with materially significant databases". In the 1980s, a low-priced dial-up version of a subset of Dialog was marketed to individual users as ''Knowledge Index''.Phyllis E. WordenKnowledge Index ''Journal of Extension'', Volume 26 Number 2, 1988. ISSN 1077-5315 This subset included INSPEC, MathSciNet, over 200 other bibliographic and reference databases, as well as third-party retrieval vendors who would go to physical libraries to copy materials for a fee and send it to the service subscriber. While being owned by the Thomson Corporation, ...

Artificial Intelligence
Artificial intelligence (AI) is intelligence—perceiving, synthesizing, and inferring information—demonstrated by machines, as opposed to intelligence displayed by animals and humans. Example tasks in which this is done include speech recognition, computer vision, translation between (natural) languages, as well as other mappings of inputs. The ''Oxford English Dictionary'' of Oxford University Press defines artificial intelligence as: the theory and development of computer systems able to perform tasks that normally require human intelligence, such as visual perception, speech recognition, decision-making, and translation between languages. AI applications include advanced web search engines (e.g., Google), recommendation systems (used by YouTube, Amazon and Netflix), understanding human speech (such as Siri and Alexa), self-driving cars (e.g., Tesla), automated decision-making and competing at the highest level in strategic game systems (such as chess and Go). ...

Sakura Wars
is a Japanese steampunk media franchise created by Oji Hiroi and owned by Sega. It is focused around a series of cross-genre video games. The first game in the series was released in 1996, with five sequels and numerous spin-off titles being released since then. The series—set during a fictionalized version of the Taishō period—depicts groups of women with magical abilities using steam-powered mecha to combat demonic threats. The original ''Sakura Wars'' was an ambitious title for the then-in-production Sega Saturn. The first game's overlap of the tactical role-playing, dating sim and visual novel genres prompted Sega to classify it as a "dramatic adventure", a moniker which has endured during the series' lifetime. Both Red Entertainment and Sega co-developed most of the games until 2008, when the series went on hiatus. Sega rebooted the series as sole developer because of fan demand. Recurring elements include anime cutscenes created by notable studios including Produ ...

Quick Time Event
In video games, a quick time event (QTE) is a method of context-sensitive gameplay in which the player performs actions on the control device shortly after the appearance of an on-screen instruction/prompt. It allows for limited control of the game character during cut scenes or cinematic sequences in the game. Performing the wrong prompt, mistiming the action, or not performing any action at all results in the character's failure at their task, resulting in a death/failure animation and often an immediate game over or the loss of a life, with some games providing a lesser but significant penalty of sorts instead. The term "quick time event" is attributed to Yu Suzuki, director of the game ''Shenmue'' which used the QTE feature (then called "quick timer events") to a great degree. However, Roberta Williams's 1984 release of ''King's Quest I'' is considered the first game to include timed events in its gameplay. They allow for the game designer to create sequences of actions tha ...

Persistent World
A persistent world or persistent state world (PSW) is a virtual world which, by the definition by Richard Bartle, "continues to exist and develop internally even when there are no people interacting with it". The first virtual worlds were text-based and often called MUDs, but the term is frequently used in relation to massively multiplayer online role-playing games (MMORPGs) and pervasive games. Examples of persistent worlds that exist in video games include ''Battle Dawn'', ''EVE Online'', and ''Realms of Trinity''. A persistent world can be achieved by developing and maintaining a single or dynamic instance state of the game world that is shared and viewed by all players around the clock. The persistence of a world can be subdivided into "game persistence", "world persistence" and "data persistence". Data persistence ensures that any world data is not lost in the event of computer system failure. World persistence means the world continues to exist and is available to players whe ...

Persona
A persona (plural personae or personas), depending on the context, is the public image of one's personality, or the social role that one adopts, or a fictional character. The word derives from Latin, where it originally referred to a theatrical mask. On the social web, users develop virtual personas as online identities. Etymology The Latin word probably derived from the Etruscan word "phersu", with the same meaning, and that from the Greek πρόσωπον (''prosōpon''). Its meaning in the latter Roman period changed to indicate a "character" of a theatrical performance or court of law, when it became apparent that different individuals could assume the same role and that legal attributes such as rights, powers, and duties followed the role. The same individuals as actors could play different roles, each with its own legal attributes, sometimes even in the same court appearance. According to other sources, which also admit that the origin of the term is not completely clea ...

Player Character
A player character (also known as a playable character or PC) is a fictional character in a video game or tabletop role-playing game whose actions are controlled by a player rather than the rules of the game. The characters that are not controlled by a player are called non-player characters (NPCs). The actions of non-player characters are typically handled by the game itself in video games, or according to rules followed by a gamemaster refereeing tabletop role-playing games. The player character functions as a fictional, alternate body for the player controlling the character. Video games typically have one player character for each person playing the game. Some games, such as multiplayer online battle arena, hero shooter, and fighting games, offer a group of player characters for the player to choose from, allowing the player to control one of them at a time. Where more than one player character is available, the characters may have distinctive abilities and differing styles ...

Tokimeki Memorial
is a dating simulation series by Konami. It consists of six main games in addition to many spin-offs. The games are notable in the dating sim genre for being highly nonlinear. Their nickname amongst their fans is the contraction ''TokiMemo''. The gameplay in ''Tokimeki Memorial'' focuses on scheduling, dating, and stat-building. The player has limited time to allocate between asking out members of the opposite sex and developing the playable character's abilities at school and sport (with the long-term goal of becoming more seductive, not out of any intrinsic value). Dates are frequent but very brief, with usually only one multiple-choice question to determine whether the partner's love meter will increase or decrease. One playthrough lasts for a fixed period of three years of high school (on the order of 5–10 hours of play), at the end of which the character with the highest love meter confesses their love. Game list Related media Manga Several manga based on ...

Tree Data Structure
In computer science, a tree is a widely used abstract data type that represents a hierarchical tree structure with a set of connected nodes. Each node in the tree can be connected to many children (depending on the type of tree), but must be connected to exactly one parent, except for the ''root'' node, which has no parent. These constraints mean there are no cycles or "loops" (no node can be its own ancestor), and also that each child can be treated like the root node of its own subtree, making recursion a useful technique for tree traversal. In contrast to linear data structures, many trees cannot be represented by relationships between neighboring nodes in a single straight line. Binary trees are a commonly used type, which constrain the number of children for each parent to exactly two. When the order of the children is specified, this data structure corresponds to an ordered tree in graph theory. A value or pointer to other data may be associated with every node in the tre ...

Tree Structure
A tree structure, tree diagram, or tree model is a way of representing the hierarchical nature of a structure in a graphical form. It is named a "tree structure" because the classic representation resembles a tree, although the chart is generally upside down compared to a biological tree, with the "stem" at the top and the "leaves" at the bottom. A tree structure is conceptual, and appears in several forms. For a discussion of tree structures in specific fields, see Tree (data structure) for computer science; insofar as it relates to graph theory, see tree (graph theory) or tree (set theory). Other related articles are listed below. Terminology and properties The tree elements are called "nodes". The lines connecting elements are called "branches". Nodes without children are called leaf nodes, "end-nodes", or "leaves". Every finite tree structure has a member that has no superior. This member is called the "root" or root node. The root is the starting node. But the conver ...
