I believe the game is too busy course correcting from the Olympus "original" direction to be a proper sandbox/simulation game.
That said I do admire what the developers have done despite this. They managed to save it from being a total failure like what happened to Sim City.
This iteration of the sims has been very strange for me.
I usually jump in at the start of new game generation and start playing my sims. This time, everything is delayed. I didn't start playing the game seriously until we received Toddlers, Parenthood, and University.
And in a way, I still won't begin to play the game seriously until all my sims have graduated university, I place all the dormies that I have come to like in their own homes, and I've edited the few remaining pre-mades to better reflect (give evidence) of the suggested lore in their household description.
I've tested that on the BFF household. Summer and Liberty actually have romantic feelings for Travis now. I've earned them some reward traits that support their given traits. I will cheat some character values that make sense for them. I have started editing their bedrooms to better reflect their personalities. I've given them a few skill points that reflect their personality, skills, and careers. I plan to give/earn them a few likes and dislikes that make sense for them. I plan to have them belong to clubs that make sense for them. There will be a sense of an existing social network.
This all intended to create a master save to replace the default start.
I want it to feel like The Sims 2 where you felt everyone lives were in motion before you first entered their world.
As it is now, the game is all talk with little evidence.
So If I decide to start a new game and a challenge, or simply a single sim, I can begin in a world that is already set the way I like with a lot of interesting sims and relationships, homes, and community lots. It will at least feel like there is a simulation at work.
