If we had some more guidance on how to get this achievement, that would be great. For example, what exactly does this mean: "without luxury need". Does that mean that no citizen can consume a luxury item or that you cannot build any buildings that creates luxury items? Did I just lose the achievement because a quest gifted me watches? What about cigars? It says it's a basic need but it's on the happiness tab of the Obrera. Did I just lose the achievement because they are consuming cigars?
If I can't build a clockmaker, can I build a goldsmith? Gold mine? Can I buy luxuries from NPCs and give them to my citizens? What about champagne? It's a basic need, but Mercier said is was a luxury. Since there's no achievement tracker it's impossible to know how you interpret "without luxury need".
There is a huge typo in this achievement.
Club challenge is correct: "Defear Dr. Hugo Mercier without luxury need public services and police station"
It includes only buildings in the luxury tab (like pub, church and theater for example). Luxury needs such as Schnapps, beer and rum is fine.
