a mainstream consensus of dating sims

from wikipedia:

Dating sim, neoromance - Dating sims (or dating simulations) are a video game subgenre of simulation games, usually Japanese, with romantic elements. They are also sometimes put under the category of neoromance. The most common objective of dating sims is to date, usually choosing from among several characters, and to achieve a romantic relationship. The term dating sim is also often used as a synonym for the visual novel genre. However, this is mixing genre and medium, as visual novels are considered a subgenre of adventure games and the term does not cover simulations. While the two genres often share a common visual presentation, dating sims are sometimes considered to be more statistically based than the "choose your own adventure" style of visual novels.

The technical definition of a dating simulation game, known as a romantic simulation game (恋愛シミュレーションゲーム ren'ai shimyurēshon gēmu?) in Japan, can involve several technical elements such as a time limit, several statistics such as looks and charm which can be boosted through exercise, or an "attraction meter" which can increase or decrease depending on one's decisions.

Visual novel games: A visual novel (ビジュアルノベル bijuaru noberu?) is an interactive fiction game featuring mostly static graphics, usually with anime-style art, or occasionally live-action stills or video footage.[1] As the name might suggest, they resemble mixed-media novels or tableau vivant stage plays.

In Japanese terminology, a distinction is often made between visual novels proper (abbreviated NVL), which are predominantly narrative and have very little interactive elements, and adventure games (abbreviated AVG or ADV), which typically incorporate problem-solving and other gameplay elements. This distinction is normally lost in the West, where both NVLs and ADVs are commonly referred to as "visual novels" by Western fans. Visual novels and ADVs are especially prevalent in Japan, where they made up nearly 70% of the PC game titles released in 2006.[2]


Visual novels are rarely produced for video game consoles, but the more popular games are sometimes ported to systems such as the Dreamcast or the PlayStation 2. The more famous visual novels are also often adapted into the light novel, manga or anime formats. The market for visual novels outside of East Asia, however, is small, though a number of anime based on visual novels are popular among anime fans in the Western world; such titles include To Heart (1997) by Leaf; Kanon (1999), Air (2000) and Clannad (2004) by Key; Kimi ga Nozomu Eien (2001) by âge; School Days (2005) by 0verflow; Higurashi no Naku Koro ni (2002) and Umineko no Naku Koro ni (2007) by 07th Expansion; Fate/stay night (2004) by Type-Moon; and Steins;Gate (2009) by 5pb.

Gameplay

Visual novels are distinguished from other game types by their extremely minimal gameplay. Typically the majority of player interaction is limited to clicking to keep the text, graphics and sound moving (most recent games offer 'play' or 'fast-forward' toggles that make even this unnecessary).

Most visual novels have multiple storylines and many endings; the gameplay mechanic in these cases typically consists of intermittent multiple-choice decision points, where the player selects a direction in which to take the game. This style of gameplay has been compared to the Choose Your Own Adventure books. Most, however, strive for a higher level of plot and character depth than the aforementioned series of interactive children's books. These can be more closely compared to story-driven interactive fiction. While the plots and storytelling of mainstream video games is often criticized, many fans of visual novels hold them up as exceptions and identify this as a strong point of the genre.

Some visual novels do not limit themselves into merely interactive fictions, but also incorporate other elements into them. An example of this is Symphonic Rain, where the player is required to play a musical instrument of some sort, and attain a good score in order to advance. Usually such an element is related as a plot device in the game.

Some shorter works do not contain any decision points at all. Most examples of this sort are fan-created. Fan-created novel games are reasonably popular; there are a number of free game engines and construction kits aimed at making them easy to construct, most notably NScripter, KiriKiri and Ren'Py.

Many visual novels use voice actors to provide voices for the characters in the game. Often, the protagonist is left unvoiced, even when the rest of the characters are fully voiced. This is to aid the player in identifying with the protagonist and to avoid having to record large amounts of dialog, as the main character typically has the most speaking lines due to the branching nature of visual novels.
The visual novel genre has evolved a style somewhat different from print novels. In general, visual novels are more likely to be narrated in the first person than the third, and to present events from the point of view of only one character. It is fairly common for the primary structural unit to be the day rather than the chapter, with formulaic awakenings and returnings to bed framing each day's events. There are of course many exceptions to these generalisations.

In the typical visual novel, the graphics comprise a set of generic backgrounds (normally just one for each location in the game), with character sprites (立ち絵 tachi-e?) superimposed on these; the perspective is usually first-person, with the protagonist remaining unseen. At certain key moments in the plot, special event CG graphics are displayed instead; these are more detailed images, drawn specially for that scene rather than being composed from predefined elements, which often use more cinematic camera angles and include the protagonist. These event CGs can usually be viewed at any time once they have been "unlocked" by finding them in-game; this provides a motivation to replay the game and try making different decisions, as it is normally impossible to view all special events on a single play-through.

Traditionally, PC-based visual novels have contained risque scenes even if the overall focus is not erotic (similar to the "obligatory sex scene" in Hollywood action films). However, the vast majority of console ports do not contain adult material, and a number of recent PC games have also been targeted at the all-age market; for example, all of Key's titles come in family-friendly versions, and two have never contained adult content at all. Also, all of KID's titles are family-friendly.

However, most of these games are later re-released with the addition of erotic scenes, or have a sequel with such. For example, Little Busters! was first released as an all-ages visual novel, but a version with erotic scenes, entitled Little Busters EX, came out later, and though Clannad is also all-ages, its spinoff Tomoyo After: It's a Wonderful Life is not. One notable exception to the rule is Myself ; Yourself, which never had an ero version, though it did contain mature content not suitable for younger audiences. Another example of this is Higurashi no Naku Koro ni.

Some of Japan's earliest adventure games were erotic bishoujo games developed by Koei.[11] In 1982, they released Night Life, the first commercial erotic computer game.[12] It was a graphic adventure,[13] with sexually explicit images.[12] That same year, they released another erotic title, Danchi Tsuma no Yuwaku (Seduction of the Condominium Wife), which was an early adventure game with colour graphics, owing to the eight-color palette of the NEC PC-8001 computer.

It became a hit, helping Koei become a major software company.[11] Other now-famous companies such as Enix, Square and Nihon Falcom also produced similar erotic games in the early 1980s before they became famous for their role-playing video games. While some early erotic games meaningfully integrate the erotic content into a thoughtful and mature storyline, others often used it as a flimsy excuse for pornography.[12] The Japanese game Pai Touch! involves the protagonist gaining the ability to change the size of girls' breasts, and the adventures that ensue in trying to choose which girl to use the power on the most.
