Depending on how far away we are from the Sims 5, I'm not sure if we will see any adjustments to teens or having tweens added to the game. I think that if they don't touch teens that tweens makes a lot of sense to implement. In the Sims 5 they 100% need more visual differences between young adults and teens. I can't stand that teens are the same height as young adults and adults. That I need to hover over sims to tell if they are teen, young adult or adult is crazy to me. I would love to see tweens, but I'm not sure if we will see them given that Sims 5 has been announced and they only have a few more packs lined up.
