Caring about your sims is not what sets Sims 4 apart (bonding with sims in 4 for me is a problem actually, where in Sims 3 it will never fail to happen; I love the looks of my latest vampire sim in 4 but her total lack of personality just spoils everything for me), it probably comes down to what we personally look for concerning the characters, looks, behaviour, I don’t know. It’s also not an explanation why IL is a good or a not so very good pack, which is the subject here. Even when you absolutely adore your sims, a game or expansion pack should simply add enough things to do for them to make their lives varied and challenging.
