And that has been a problem for a while now. What I do not like with these trailers are that they are using custom animations to give an impression that sims are reacting in ways that they do not in the game. They are also using sims that they have made themselves, not randomly generated and they are using way more in the shot than there is normally in the game, the game has a restriction of 20 sims per lot.

And what I really don't like are that those animations are there, we can see them. But they do not add them to the game, so they create them just for the marketing trailer. And they do not give us any options to edit the situational outfits or if the game should pick from existing sims or randomly generate new ones.
