Chemistry: Difference between revisions

Each teen, adult and elder Sim has two turn-ons and one turn-off. Turn-ons and turn-offs are designed to make relationships easier (or harder) to achieve. For [[Townie#The Sims 2|townies]] and Sims made before ''[[Nightlife]]'' these are chosen at random. So these Sims are not locked into these random choices, they will usually receive a potion called the [[ReNuYu Porta-Chug]], which allows the Sim to change their turn-ons and turn-off. Turn-ons and turn-offs can also be changed by using the [[ReNuYuSenso Orb]], which is an [[aspiration reward]]. If ''[[University]]'' is installed, [[college]] Sims can change their turn-ons and turn-off, as well as their [[Aspiration (The Sims 2)|aspiration]], when they finish their Sophomore year. A Sim's turn-ons and turn-off can also be changed with [[SimPE]]. If changes to a Sim's turn-ons, turn-off, or aspiration would affect his or her chemistry with another Sim, the changes may not appear until the next time the two meet face-to-face.

Turn-ons and Turn-offs are not the only contributors to Sim chemistry. Chemistry is determined based on the attraction score between two Sims. This attraction score is calculated from each Sim's [[zodiac]], primary [[Aspiration (The Sims 2)|aspiration]], current [[personality]] (not genetic), turn-ons, turn-offs, and any additional effects that affect attraction.[http://web.archive.org/web/20090221124229/http://thesims2.ea.com/help/detail.php?help_id=177] All of these factors are added up to produce the attraction score and averaged to find the chemistry. Thus, one Sim may be more attracted to the other, yet both would have the same chemistry score. The actual calculations for these scores are slightly complicated, but easy to understand.
