It's really very interesting.
I've got both.LN has got very interesting thinks,like skyscrapers,the only thing I don't like is that you can't built your own

^^You can, you know. LN is still my fave expansion. Agree that S/Time makes it even better. For me 1st prize is coasterboi's Los Anigos late night edition world, as it fits all of the expansions and stuff packs in with room to spare.
That said, I always find myself ending up in Bridgeport. There is space to have more family houses, and I usually have my sim start on an empty lot and live in the Park which I edit in Edit Town to have everything you need. I have found the only way to stop everyone turning into vamps is to play with story progression off. Have personally found that playing with aging on and having all lifespans on Epic is pretty cool. If you're playing families you just reset the baby, toddler and child, and the teens are fun. In fact, if you like the idea, my Edited version of Bridgeport Acres is in my studio for download to save you the hassle. I played most of the families to a lvl they can survive, and replace the game copies with mine so I don't have a bunch of sims die because of hunger, and miserable cause they pee themselves in public! lol.

I think out of all the expansion packs, it adds the most content. I want to buy generations soon but right now I own Late Night, and I am really happy I bought it. Celebrites really make you look at sims in your town in a new way. It also comes with Bridgeport. I love Bridgeport because it gives you alot of clubs and bars and also modern apartment, but I do wish you could have more space to build your own houses. Late Night will get boring if you play it for a super long time, but I still think it offers you really great things to do.

Late night is a great expansion but can become quite boring (in my opinion) Also, when I play in Bridgeport my game seems much slower and objects and buildings take longer to load, I'm not sure if this is something to do with my laptop though..

No I have Showtime and Generations and Late Night and my sims can spend hours in the LN clubs eating,drinking,hottubing and dancing along with using the bubble blowers. I'm still not board of Late Night.

The LN clubs are a lot funner then the ST clubs.

^^^ I fully agree with you.
@Megan, it would lag more, there is more to 'render' I think. Everytime I have to play on my back up computer, I find myself thinking the game has 'frozen' cause I'm used to the power on my usual rig. I think it has something to do with the CPU, cause my backup has a decent PSU. [not a comp. whiz, just understand my hardware!lol]
