There are many careers that you can get your Sims character involved in. Some of those careers that are included in The Sims 2 are business, military, medicine, law enforcement, science, athletics, and even politics. Of course you can get one of the expansion packs such as University, Seasons, or Free Time and it will add more career options for you to choose from. When your character gets into a career and does well at it you will see a career reward opened up. Most of them help you improve a skill that is important to your career. You can even retire if you continue to work until reaching the life stage of an elder. You even get a pension payment daily when you retire, the amount of which is determined by what career you retire from as well as the level in which you did your job.
