Does this pack feels like PSa ?

I don't know. To me it seems more like they picked a Sim, imagined her to have a certain personality (which is something I also do while playing) and had her explain some gameplay aspects from her view. The problem for me was that I found her personality annoying as heck, which is why the trailer didn't speak to me as much as it could have. Maybe if they had picked a Sim like Knox, who is trying to get the votes for his community garden or a Sim who looks for treasures in the trash and uses the machines in the community maker space to upgrade stuff, that might have been more engaging.
