What Sims 4 got wrong and brings me back to Sims 3. Can still be fixed!

The way I see it, The Sims 4 is like a toy, like a dollhouse. There are very few opportunities for immersion; everything feels like a play in which your Sims are the main characters and the world revolves around them. In The Sims 3, your Sims are part of a much larger ecosystem and the town functions as a whole. This made the game so much engaging for me. Not to mention the lack of unique personalities and traits that actually do something, the result is a like playing with dolls rather than playing an open ended life simulation game.
