Cities: Skylines - Sunset Harbor (DLC)

Sunset Harbor is a content DLC for Cities: Skylines that arrived after the base game had already established itself as the dominant city-builder on PC. It bundles several distinct systems that players had been requesting or replicating through mods: a fishing industry chain, a new intercity bus and aviation hub framework, and the Inland Water Treatment Plant that finally gives water management a credible late-game layer. If you have been running a metropolis of 100,000 and feeling like the simulation has plateaued, this pack targets exactly that ceiling. The fishing industry is the headline feature and it holds up. You place fishing harbors on shorelines, assign fishing boats, and feed catch into a processing and export chain that plugs into the existing industry specialization model. It is not a radical reinvention - if you have played Industries or Green Cities you already know the rhythm of supply chains in this engine - but it adds a sensible coastal economic identity that was conspicuously absent before. Paired with the new fish market building, you get a reason to actually design waterfront districts rather than just parking them out of sight. The transit additions are where number-crunchers will spend most of their attention. The intercity bus terminal and the expanded aviation cluster let you model how your city connects to a simulated outside world, which feeds back into tourism and commuter demand in ways that force you to think about your transit network as a regional system, not just internal routing. The new pedestrian street zoning tool also shipped with this DLC and it is quietly one of the most impactful additions in the entire DLC catalogue - it lets you designate car-free zones that generate organic foot traffic, which changes how you think about downtown density and transit stop placement entirely. On the downside, Sunset Harbor carries the usual Colossal Order caveat: some systems feel undertuned for very large cities. Fishing boat pathfinding on congested waterways can get messy, and the aviation hub mechanics do not scale with the same elegance as the road-based transit tools. The DLC also predates several later patches and expansions, so a handful of its UI flows feel rougher than what you get in more recent packs like Airports or Financial Districts. None of this is a dealbreaker, but if your city is already running on a stack of traffic mods and asset overhauls, expect the occasional quirk. For newcomers asking whether to buy Sunset Harbor alongside the base game: yes, but treat it as a second-phase purchase. Learn the base zoning, road hierarchy, and budget loops first. Once you are building cities that push 50,000 residents and want to add economic specialization and serious transit depth, this pack gives you meaningful decisions to make. The fishing chain is approachable, the pedestrian zoning alone is worth the price of admission for anyone who cares about realistic urban form, and the overall scope is honest - it expands the game rather than wrapping old content in new UI.
