Gameplay in
The Sims basically consists of creating one or more people, building (or buying) a house for them, and then attempting to keep the people happy. When a new game is started, one crafts the personality of each person, allocating points to five attributes: Neat, Outgoing, Active, Playful, and Nice. These in turn govern how the Sim will interact with their environment and others.
Happiness in The Sims, like in real-life, is complex, and consists of eight variables called Motives. They are Hunger, Social, Comfort, Fun, Hygiene, Bladder, Room, and Energy. These Motives are satisfied by having The Sims eat, socialize, rest, enjoy entertainment, bathe, use the restroom, gain a more spacious abode, and by sleeping, respectively.
Depending on a given Sim's personality, some of these Motives are taken care of automatically, and others require direct intervention. For instance, one Sim may go to the restroom by himself, whereas another would require direction to use the facilities. And this is the crux of gameplay in The Sims, as it is really an experiment of sorts, where you get to create, control, and watch these people, and it proves quite fascinating.
Whereas the gameplay doesn't really differ from that offered on the PC. The new 'Get A Life' Mode is task oriented, and it serves as both tutorial and mini-game. It presents a given scenario, a set of tasks, a person to routinely remind you of those tasks, and then all of the tools to complete it. This console specific mode must be completed before one can play the free form 'Play The Sims' Mode.
'Get A Life' Mode will take someone five to ten hours to complete, but given the number of options available, the wide open nature of the game, and its addictive nature, it could take much longer. It is really a welcome change of pace from 'Play The Sims'.
