What did the sims 4 do better than previous games ?

The sims in the sims 4 are definitely easier to look after, its takes a long time for sims too die because of their needs the sims in previous died too easily, multi tasking, I like that my sim can drink, eat and talk at the same time, This is my personal opinion but i love the fact we cant control cats and dogs, this time around, I like that they have a mind of their own like real life and you have to figure out what's wrong with them, I also love that we have a vet and it can also be your sims career
