Why does a game from 2003 has better NPCs than Sims 4?

Dear Sims developers,

Please bring your AI up to the level that Nintendo and Namco already achieved in 2003 with the first Animal Crossing on the Nintendo DS.

It’s frustrating that in The Sims 4 — a modern game with dozens of expansions — NPCs barely act on their own. They don't fix things, don't pay bills, barely follow routines, and seem to freeze when they’re not part of the active household.

Players want a living, breathing simulation — not a micromanagement sandbox where every detail needs direct control. A simple setting like "Enable Full Autonomy" would be a huge improvement. 

I love Sims 4 - Please add this Setting.
