How does Reputation affect gameplay?

I've been playing a lot of sims but mostly I'm noticing opportunities to get a better jobs out of the blue for both good and bad reps. The jobs will align more with the rep of course.. like the criminal career can be offered to bad rep sims, and more. You get offers for blind date set ups. My bad sim got set up with Judith Ward.. I had fun with that. Otherwise none of my sims that I'm driving to a good or a bad rep really have much fame so I haven't started on what the fame points will do there. Oh and when you meet new sims the rep affects that.. my bad sim is having to work at it a little more unless the sim they meet is bad too.
I only played with one sim with a roommate so far and it seems to only affect individually... could be wrong there.
