If you don’t follow Shannon Copur/SimGuruShannon on Twitter then you might want to start since she shared all of these screens a couple of days ago.
Some are of loading screens that “didn’t make the cut” and some are of concept art turned in game items.
There are also two screens of content filtering in Build Mode. They all look pretty cool. Personally, I can’t wait to get my youngster sims in those tree houses and on the water slides.
