In general, everything goes along very well. I have just finished the concrete sea wall that surrounds Manhattan.
The city comes more and more alive due to several lots I have added over the last two weeks. Storefronts, interactive places like Starbucks Coffee, appartments, high-end lofts and so on enhance the gameplay and add to the atmosphere.
You may have already seen Rockefeller Center with the GE building in the New York Winter Nights post. It's a seasonal lot and so it changes over the year. In winter you will have the famous christmas tree and the ice rink, in summer there is a stage for concerts and so on.
I have finally managed to make the Empire State Building become an interactive lot with a basement featuring boutiques, shops as well as Walgreens and Starbucks. There is still some work to do here, but I am quite confident with it right now.
Your Sims can also take the elevator to the observation deck and enjoy a fantastic view over the city.
If you are a couch potato and prefer to stay at home rather than straying through the city, this luxurious penthouse near Central Park could be just right for you.
Those are just a few examples. Next time I will show you St. Patrick's Cathedral, The New York Live Building and some more. Please don't mind that I can't tell you when it will be finished. I am doing my best to get it done as quick as possible.
Stay tuned ;)
