There's always Anno 2070, though I'd be surprised if you hadn't already played that.
Have you tried 'Towns' ? http://www.moddb.com/games/towns
I'm hoping games like Prison Architect could be the start of a whole new 'Tycoon' franchise. Personally, I want a HighSchool Architect, imagine the Curriculum/Lesson Planner? Nothing but Dinner, breaks and Physical Education, bottled with immense micro-management of teachers and students, enabling/preventing school-shootings & food-fights. Maybe dis/encourage bullying? It'd be wicked.
