If this game were a hamster, it'd be dead by now. Version 4.0 was released nearly two years ago. That's not to say that there's any detectable level of lameness here. Your Sim is a little cartoon human in a little house in a little neighborhood. When it's hungry, you tell it to make itself some lunch.
Simple actions can have big consequences.
Watching TV makes your Sim happy, but watching too much TV will lead to, well, watching way too much TV, which means it won't socialize with the other humans and won't do well at work. The game is fabulous eye candy. It's like an ant farm, except the ants are in color, and they wear pants. In theory, you want to manage your Sim's life to ensure its personal happiness, fulfillment, and career success. But many play The Sims to lose.
