make them all mad

🏭 1. Maximize pollution
Place industrial zones directly near residential areas.

Place water pumps downstream of sewer pipes – this way, your citizens will literally drink their own wastewater.

Don't remove mountains of garbage: Let the landfills fill up and ignore garbage problems.

🚫 2. Ignore basic needs
No access to education: Don't build schools or universities.

No healthcare system: No hospitals, no funeral homes → illnesses and corpses pile up.

Cut off electricity and water supplies: A classic way to cause immediate discontent.

🚓 3. Chaos through crime and fire
Don't build police or fire stations – crime will rise, buildings will burn uncontrollably.

Extra nasty: Only build emergency forces in wealthy neighborhoods and ignore the poor neighborhoods.

🛣️ 4. Create traffic hell
Pointless road layouts, e.g., endless roundabouts or dead-ends with no turning options.

Eliminate public transport or connect them pointlessly.

Overload traffic lights and intersections so that traffic jams paralyze the entire city.

📈 5. Raise taxes, lower services
Raise taxes to the maximum (12–29%) – especially for residential areas.

At the same time: Set all services to 0% budget – no one cleans up trash or heals the sick anymore.

🧠 6. Unrealistic urban planning
Build residential areas right next to airports or train stations – noise makes everyone unhappy.

Eliminate parks or recreational facilities.

Mix zones haphazardly: industrial areas, residential areas, prisons, and wind turbines right next to each other.

🌊 7. Disasters and Mods (with DLC or Mods)
If you have DLCs like "Natural Disasters":

Use tsunamis, meteors, or tornadoes to your advantage.

With mods like "God Mode," you can deliberately wreak havoc (e.g., zombies or nuclear reactors).

🔚 Conclusion
Intentionally making your population unhappy is a surefire way to bankrupt yourself—but also a fun way to learn the game mechanics. Or simply to see how much your Sims can endure.
