I'm hoping sims 5 will have more lots. I know the Sims 4 worlds are all "connected" but they still just seem small. But I in no way expect as many lots as possible in Sims 3. If Sims 3 had 100-150 lots possible and Sims 4 is more like 15-25 I'm hoping for a good 30-40 lots in Sims 5 worlds. I'd be surprised if it was more than that. I do hope they have neighborhoods again of 5-10 lots each, and the neighborhoods are open. I don't expect we'll have completely open worlds again.
