A life simulation game can revolve around "individuals and relationships, or it could be a simulation of an ecosystem".
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 incorrectly in English as a generic term for romance-driven games (ren'ai games), a subject matter which is stereotypically associated with the visual novel genre.
You can dump your current girlfriend anytime and construct a new one using your newly increased status points.
Eventually, when your status reaches 100, you can construct The Perfect Woman to fulfill your ultimate goal in the game: get into the Big Party which only accepts "perfect" people.
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.
