Eroge only gets released to PC because large Japanese game companies do not want to release games with sexual content on their game consoles.Because of this, Eroge companies make a censored all-ages (15 ) version of the PC version for various consoles.
When the game ends, the player either loses the game if he failed to properly win over any of the girls, or "finishes" one of the girls, often by having sex with her, marrying her (as in Magical Date), and/or achieving eternal love.
This gives the games more replay value, since the player can focus on a different girl each time, trying to get a different ending.
The Star Ocean series of RPGs also feature dating sim elements in a similar manner.
Some Japanese dating sims may allow the player to have romantic or sexual relationships with characters in their teens.
Regardless of race, creed, species, plane of existence, or definition of "alive," your perfect match is waiting for you somewhere in the great cosmos.
And when it comes to, shall we say, couples, no one tops the open-minded pairings found in dating sims.
There are also GL games, which focus on female/female relationships, and BL Games, which focus on male/male pairings.
There are many variations on this theme: high-school romances are the most common, but a dating sim may also take place in a fantasy setting and involve such challenges as defending one's girl from monsters.
The technical definition of a dating simulation game, known as a romantic simulation game 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.
