The future comes with some great technology and stuff that you can buy for the present day house. Stairs have been one of my greatest challenges when trying to build my own house. It just seems that I can never get them exactly where I want to. Now, that isn’t a problem at all. I just put an elevator pretty much anywhere I’ve got room on top and bottom (I usually use a corner) and my Sims can quickly get from one floor to the next. I highly recommend getting rid of your outdated stairs in favor of an elevator that doesn’t cost too much!
The other big thing that I recommend is getting rid of all your beds in favor of a dream pod. Your Sims will want one anyway, so give it to them. Instead of just sleeping, you can now choose what your Sims will dream about. Be careful because dreams can be very powerful. If you dream of different personalities, for example, you might wake up with completely different traits than what you went to bed with. Dream can be good though, increasing your adeptness at learning skills or your good will towards family and friends. You can even have your Sims join in another Sim’s dreams.
I must mention that there are quite a lot of new clothes and items that also look perfectly futuristic. You can create an entire house in the present that will make you feel like you’ve traveled to the future without actually going there. Your Sims can become the most fashion-forward people around.
