Slice of life adds a whole menstrual system for your sims which is so realistic and it’s really flushed out too, they’ll need to change their period products and even take medicine to make their cramps go away.
Your sims can have a skincare system and get acne if they don’t use their skin care appropriately. They can have appearance changes when they have emotions like tears in their eyes when they’re sad or rosy cheeks when embarrassed. The first thing that this mod adds is a memories system where your sims are able to remember and talk about important moments in their lives. This mod has so much going on inside of it and really adds realism to so much of your game. Slice of Life is one of the first sims 4 realistic mods I ever download and I’ve never gone back.
