I enjoy playing this game, and I bought it few years ago. I like that it's replayable.
Building is great, and with some additional tools it would be awesome. CAS has lots of variety so I can create different sims and pets.
I enjoy collecting and gardening, different clubs, beautiful worlds especially with seasons. I like emotion system and multitasking. Family play is expanded, there are realistic toddlers and pets, and I like to hire butler for riches, holidays etc etc. And I enjoy active jobs and would like more of them. For me it's lots of gameplay.
