The most common objective of dating sims is to date, usually choosing from among several characters, and to achieve a romantic relationship. This can lead to confusion, as visual novels are considered a subgenre of adventure games and are not technically included in the dating sim genre. 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 romance simulation game 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.
