I've always thought The Sims 4 lacks depth in game play. Everything feels so surface level and I can't get into it like I could with The Sims - The Sims 3. I've gotten all the packs as well and I feel like more content can't fix a game that just doesn't work at the base level. I personally think they need to overhaul the traits and personalities of sims to make them more unique beyond just their physical appearance. I know it's been an area of disappointment for a lot of players, myself included, that teenage sims are the same height as adults. They just don't feel like teenagers to me.
