More furniture, clothes, jobs, plus the ability to have babies would improve the shelf life of The Sims 3 for Android.
The gameplay of The Sims 3 is fun and addictive, though the game doesn't have as much longevity as console and PC versions of this strategy game. From time-to-time your Sim will have a 'wish' that he or she wants to fulfill (catching fish, insulting someone, etc.) and you must help them achieve this to make them more happy.
You need to take care of yourself (eating, sleeping, using the washroom, etc.), find a job, make friends, and go shopping. Once you've customized the appearance of your character, you're dropped into a house in the world of The Sims 3.
