I recently got the base game, and decided I'd buy one EP (as I doubt my computer would run all the EP's). So I read through all the games and decided on LN. I found it very confusing to start with due to the apartment buildings, and it took forever to get anywhere. Even when I had a pregnant sim, her husband went in the car to the hospital, but as it was designated as HIS car, she took a taxi then the subway! By the time she got to the hospital, I think she has the baby in the hospital foyer lol.
I like the stuff from LN, but I tend to play Sunset Valley and make my own clubs/music venues.
Bridgeport is, like the others said, not really about families. It's about young, single Sims that like to party lol. Most apartments are either studios or one bedroom, the houses are one bedroom, too. Even the big mansions across the bridge often have one bedroom.
