I only got sims 4 a couple of days ago, but prior to that, I hadn't played the Sims 3 for a while (which tends to happen when I get a new video, this case being Last Of Us). I will definitely go back to Sims 3, as I only got the game less than a year ago, and I tend to get expansion packs when they are on sale, so a lot of the game is still new to me and I still have a lot I can do with it. Plus there's a lot of features in 3 that I miss from 4. I did spend a lot of time on interior designing in 3, because it's something I enjoy. I can do that in 4, but without create a style and limited furnishings etc, it's not as fun....yet.
