Sims who are level 4 or above in a lifetime emotion skill can reminisce about an emotion while they’re already in it. This means Sims will no longer be neutral one minute and suddenly gain a +4 Inspired Moodlet. Unlike Affective, which had Sims enter a Moodlet of a specific level based on the skill, Experiences has Sims enter a Moodlet based on a random chance depending on the skill level, which can build up and increase if the chance is triggered while the Sim already has it. Poor Sims will remember most emotions faster than rich Sims, with the exception of Angry and Confident, which rich Sims remember faster. A Sim’s financial status now also effects how quick they remember their experiences. Just like with Affective, younger Sims will build their lifetime emotions faster than older Sims. Bored and Tense no longer have their own skills (while they did in Affective) but will instead boost Sad and Angry respectively. There are lifetime emotion skills for Angry, Confident, Embarrassed, Energized, Focused, Inspired, Flirty, Playful and Sad. There are also other features related to a Sim’s past and the condition they’re in.
This means that what your Sims do will have a greater effect on their future. Its main feature is that when Sims are in a certain emotion, they will build a “skill” based on that emotion, which enables Sims to randomly gain a Moodlet based on their past experiences.
The Sims 4 Experiences Mod Pack is a revamped version of Affective combined with my abandoned Cradle-to-Grave mod.
