I agree that Sims 4 definitely needs more base game work regarding Sim depth. It still feels incomplete to me. I feel that same frustration with trying to create Sims with individual behaviors, only to have them all feel too samey. Between that and the missing Fear emotion, the game will always feel unfinished to me. I just hope there are some changes on the agenda for the future in these areas.
As far as Sims 3 packs, I was able to get a bunch of them on sale for $5 each over a year ago, so if you hold out for sales, you can eventually get them on the cheap. I think I bought some on Amazon for that price as well as on Origin. But Origin sales seem rare for Sims 3, (as far as I can tell, but I honestly don't look it up much) so searching elsewhere might be more beneficial. For the cost of one full-priced EP I was able to get many, so that was nice. I don't really play it, though.
