It’s one thing to read about all the new stuff in Late Night and whole nother thing to actually see it with your own two beady eyes.
I can tell you from personal experience that not all of the changes are exclusive to Late Night. The new patch – 1.17/2.12/3.8/4.5/5.2 – improved the look of the skin, added new slider functionality like making the muscle definition controls much more sensitive and adding a breast size slider – a feature that was only available before this patch with the addition of a custom content slider.
The 1/2 wall is back and now you can create fountains on private and public lots and customize pool edges – no more water boxes.
As far as added functionality, this seems to be one of the best in a while.
With regards to Late Night, tons of things have been added and brought back and not just Vampires. The “bubble machine” is back as is the hot tub and the elevator.
Take a look at this long video [over 7 minutes] to get a look at a bunch of the new Late Night items.
