Check it, yo!
The core gameplay is the same as in The Sims 3: control every aspect of characters’ lives, from woohoo to work performance, trying to juggle it all so that they don’t wind up miserable, stinky or fired. Unless you’re a sadist, in which case go nuts. But your pets are now playable, too.
Their moods are less volatile than humans’ – who often seem curiously depressed by the antics of their furry friends – and they can be kept awake for longer, meaning no more dull minutes spent fast-forwarding through the night.
It’s nice to have some diversion while the rest of the household is at work/school, but the pets’ fairly limited range of actions, such as scratching furniture and digging up the garden, does lose its novelty after a while.
