Cities: Skylines - All That Jazz (DLC)

Cities: Skylines - All That Jazz is a cosmetic DLC for Colossal Order's city-builder, adding a themed collection of jazz-inspired props, buildings, and decorative assets that lean into a mid-century, New Orleans-adjacent aesthetic. It is not a mechanics expansion. There are no new zoning types, traffic systems, or policy levers here. What you get is visual vocabulary - the kind of stuff that makes a screenshot worth posting and a downtown district feel like it has a personality rather than just a tax base. For players who already own the base game and have a city or two under their belt, this pack slots in cleanly. The assets show up in the relevant menus without any configuration, and Colossal Order's asset pipeline is stable enough that nothing here is going to break a save or conflict with popular workshop mods. If you run a heavily modded install - think Ploppable RICO, Network Extensions, or Fine Road Anarchy - these props sit alongside workshop content without friction, which matters more than it sounds. Where the DLC earns its place is in the mid-to-late build phase, when your city has solved its sewer overflows and transit death spirals and you want to start caring about what things look like. Placing jazz-club facades along a pedestrian boulevard, or dressing up a plaza with thematic props, is genuinely satisfying if district aesthetics are part of your workflow. It is not for players who are still figuring out roundabouts. The tutorial does not cover decorative assets, and newer players will get more mileage from gameplay-expanding DLCs like After Dark or Mass Transit before circling back to cosmetic packs. The honest caveat is that Skylines has a massive free workshop on Steam, and a motivated player can find comparable - sometimes better - jazz-age assets uploaded by the community at no cost. All That Jazz is essentially a curated, officially supported slice of that same creative space, with the polish and compatibility guarantees that come with an official release. Whether that trade-off is worth it depends entirely on how much you value curation over quantity and official support over DIY. Bottom line for the spreadsheet-minded: this DLC adds zero decision-making depth. It will not change your city's efficiency curves, and it will not affect late-game sustainability. It is a cosmetics line item, priced accordingly, and should be evaluated purely on whether its specific aesthetic matches the cities you like to build. If jazz-age urban charm is on your mood board, it delivers. If you are still optimizing bus lines, come back later. Diego, Scout Team
