I don't think Paralives will even come close to the same scope of the Sims franchise and people looking for an alternative will find something much simpler, which is probably not what they were looking for since a lot of people were already disappointed by the Sims 4 and how dumbed down it was.
If they built a rich simulation, that could make it appear larger without the extra manpower behind it. It'll be interesting to see no matter what, assuming it also doesn't get canceled.
