Open worlds discussion

I loved the worlds in sims 3 as I enjoyed being able to have plenty of residential lots and commercial. I was able to have a "town" and put in restaurants, bowling alley, roller skating and many more commercial lots to give my sims plenty to do. I always was able to meet other sims on these lots. I also loved going on world adventures on vacation. They also added where your sims could move to another of the worlds as well. One of my disappointments with Sims 4 from the start has been the limited room available in a neighborhood. I would love to add pizza shops, restaurants and more to make the towns a real town, but it would be at the expense of losing residential lots which I also don't want to do. Now I use Newcrest for most of my commercial lots so my sims have a place to go for fun. I have adjusted my gameplay to the way Sims 4 works and still enjoy playing, but still find it limiting.
