I like the depth it gives to romantic storylines and it greatly enhances romance as a whole. It does come with a LOT of notifications and micro management though, so if you like this kind of playstyle, go for it!
To be noted, paired with all of the others EPs I feel like I get interrupted every 3 secondes, between notifications, popups and phone calls, and this EP adds a lot. You get a notification each time you discover one of the other sim traits because it constantly updates the chemistry between them 😆
It's more of a "things happening in the background" kind of pack than other packs, and some things are badly tuned (the default rate at which the "relationship satisfaction" decays, for example) so if you play on PC definitely get some mods that make the gameplay experience better.
There are so many little things and details in the pack and it's really goofy in a sims way, which I really appreciate.
