</>Common questions about Cloud Nine
What does Cloud Nine do in Cities: Skylines?
Cloud Nine is a Cities: Skylines mod that keeps every building across your city perfectly happy, so your overall city happiness climbs to the top and stays there. Traffic backed up, trash piling up, a power outage or two — none of it dents the mood while Cloud Nine is on. That makes it great for experimenting with wild, impractical layouts without watching residents pack up and leave, or just for enjoying a stress-free, feel-good city. It's a master switch: on means everyone's grinning, off means vanilla mood management is back in your hands. Cloud Nine is a free ProjectMods mod, installed in one click through the ProjectMods desktop app.
How does Cloud Nine keep city happiness maxed out?
Cloud Nine works at the building level in Cities: Skylines: rather than nudging a single citywide number, it keeps every individual building beaming with full happiness, and your overall city happiness reading rises to match. Because it covers buildings across the whole map, the usual things that would normally drag mood down — congestion, uncollected garbage, patchy services, the odd blackout — stop pulling your happiness score down while it's on. The effect holds steadily rather than flickering, so you get a consistently top-tier mood instead of a figure that dips every time something goes wrong. Flip Cloud Nine off and each building goes back to reacting to its own conditions again.
Does Cloud Nine stop citizens from leaving abandoned or unhappy buildings?
Because Cloud Nine keeps every building in Cities: Skylines happy, the abandonment and move-outs that unhappiness normally triggers largely stop while it's on — which is exactly why it's so useful for testing risky layouts. You can lay out something wild and impractical, and residents won't pack up and leave over the usual complaints. It's worth knowing what Cloud Nine covers, though: it manages the mood of buildings, not every unrelated system in the city. Core mechanics like traffic, services and your budget still run normally underneath — you're simply keeping everyone content on top of them. Turn it off and buildings begin reacting to their real conditions again, including leaving if things are bad enough.
Is Cloud Nine a single switch, or can I set happiness per district?
Cloud Nine is a single master switch in Cities: Skylines rather than a per-district or per-building control. On means every building citywide is kept perfectly happy; off means vanilla mood management is fully back in your hands. There are no sliders or zone-by-zone toggles to manage, which keeps it predictable — you always know the city is either running on guaranteed happiness or its own reactions. That simplicity is deliberate: Cloud Nine is meant to be the stress-free everyone's-smiling button, not a fine-grained mood editor. If you want some districts happy and others struggling, you'd leave it off and manage services the normal way; when you just want a feel-good city, one flip covers everything.
Why would I use Cloud Nine in Cities: Skylines?
Cloud Nine is for two kinds of moments in Cities: Skylines. The first is creative freedom: when you want to experiment with wild, impractical layouts — a city built around aesthetics rather than efficiency — without residents abandoning it the second services fall short. The second is pure relaxation: sometimes you just want a calm, feel-good build where nothing sours the mood and you can enjoy the view. Keeping every building happy lets you focus on design and screenshots instead of firefighting complaints. When you want the normal challenge of balancing services and mood back, flip the switch off and the city reacts to your decisions again. Cloud Nine is free from ProjectMods, the community-first modding platform.
