Each job has a bar that you have to fill up in one day to do the best performance you can. One job has you starting at the bottom and working up till your a master detective. Something we've all wanted for years we finally got a respectable version of it. It would of gotten a great 8 out of 10 if they had put a tad more time into it and made every job interactive, but the 3 jobs that they did do, are fantastic. This expansion made the Sims 4 worth buying in my opinion.
