Speaking of the sims in Sims Four, sims have free will but their fate is ultimately decided by you mostly. Same with the Creator of the matrix, you have free will but unfortunately, the creator has some to say about it
Sort of, but they've limited everything. You cannot directly kill a Sim anymore unless you starve them. You can't drown visitors. You can't set fires. And the AI is very limited. If you let the game do what it wants, the sim doesn't always do the right thing and could starve to death. I hope they improve this so you can just let the game run and watch them reproduce and get jobs on their own. They could occasionally buy things like a coffee pot, too. That would be a cool feature.
