I was starting to wonder if maybe Colossal Order was done with Cities: Skylines, or they had moved on to development of a full sequel. After releasing two expansions per year since the game's launch in 2015, we've now gone almost a year between expansions. The last one was the Campus expansion last May. Now here we are with a new Sunset Harbor expansion.

The announcement for this expansion (a mere week before its release) got my hopes up in a similar fashion to the Snowfall expansion. I thought that Sunset Harbor would add a slew of features that I had been longing for in the game for a long time. Sadly, Sunset Harbor disappointed me in much the same way that Snowfall's lack of a seasonal cycle and poor implementation of ski resorts did. Sunset Harbor lacks almost all of the things that I had hoped for, and it continues a trend of Skylines expansions that add new mechanics or content without revising or enhancing existing mechanics or content to utilize the new ideas.

When I saw the title of the expansion, I thought for sure that this would be the expansion that would finally introduce public beaches! No such luck. There's no public beach area. Sunset Harbor (despite having "harbor" in its title) does not introduce modular passenger and freight harbor areas, or upgrade harbors into a leveled industry like Industries did with agriculture, forestry, ore, and oil. I still can't daisy-chain my harbors to send shipping routes up rivers or canals, despite the fact that the existing passenger ferries and the new fishing industry can. It similarly doesn't convert tourism and leisure into leveled industry or commercial areas.

As always seems to be the case with Skylines expansions, I'm torn between whether I should review the expansion from the perspective of what it actually brings to the table, or from the perspective of failing to meet my own hopes and desires for what the expansion should be.

One of the things that was missing from Industries

Sunset Harbor does, however, check off a couple items from my wishlist. At long last, it has provided a desert biome map! As someone who lives in the American Pacific Southwest, I've long been frustrated by the inability to create a city that looks more like the familiar landscape of my own back yard. Now I finally can. Sadly, it's only one map, but the asset editor that's always been included in the game will allow me to make more if I want to, without having to resort to downloading mods that might destabilize the game.

I've long hoped for a desert biome to be added to the game.

The big feature of this expansion is also a feature that I thought was missing from the Industries expansion. I complained that Industries only added new infrastructure that replaced the existing agriculture, forestry, ore, and oil industries that have always been in the game, and didn't bother to add any new industries. Parklife, by comparison, added a couple new types of parks that hadn't been in the game before, including nature preserves and an amusement park. Personally, I thought that the most obvious option for a new industry to add to Industries would have been a fishing or aquaculture industry. Well, now we have a whole expansion that has added that one idea.

The new fishing industry doesn't follow suit with the Industries expansion industry areas, or the Campus university areas. You don't paint aquaculture areas and then grow them and level them up. There's no complicated production line or logistic element. The different types of fish that you can catch also don't do anything different. There's no fancy factories that consume specific types of fish (like a pizza factory that consumes anchovies), or that combine your fish with other types of fish (like a fish stick factory), or with other industry products to create a more valuable luxury good (like combining fish and seaweed with crops to make sushi).

Aquaculture does not level up or have production lines like other industrial sectors.

Instead, there's a handful of fishing harbors that act as resource-extractors, and then there's exactly two buildings that process or consume them. Your fishing harbors can either sell their fish to a market to be sold directly to consumers, or the raw fish (regardless of type) can be shipped to a factory that processes the fish and distributes them as generic goods to send out to commercial zones. In lieu of either the market or the factory, the fish will be exported to other cities for a small amount of money.

That's it! That's everything that fishing has to offer!

...

Hot off of releasing a video in which I criticized Colossal Order's design philosophy for its Cities: Skylines expansions, a new expansion was released. This expansion fulfilled my fears by being similarly narrow in scope compared to the previous expansions. Campus might even be more narrow than previous expansions. Every city will need parks and industries, so you'll have plenty of opportunity to use those expansion features in every city you build. Not every city will need a sprawling university complex, so a given city might not ever need to include any of the Campus content.

Fortunately, there's more options here than a full-blown research university. Colossal Order has added several types of university areas that are more suitable to modestly-sized cities. Sure you may not need that full-blown research university, but maybe your smaller town could use a trade school or liberal arts school?

Even so, the scope here is very narrow! Colossal Order seems to have recognized this, as they are selling the expansion for a couple dollars less than previous expansions.

School is back in session, even for your industries!

Since Mass Transit, new expansions have struggled to find ways to make broader impacts on the game as a whole. They mostly stayed in their lanes. Campus follows suit by not adding anything that isn't related to education, however, those overhauls to education do have some further-reaching ripple effects.

Over-educated citizens used to refuse to take lower-level industrial jobs.

One of the problems that players have had to deal with since the initial launch of the game has been over-educated workers. Once you have schools in your city, it's only a matter of time before virtually everyone has a high level of education -- even children. This would leave all those educated citizens unwilling to take low-education, low-paying jobs in your factories and farms and would starve those industries of eligible workers. Demand for high-end commercial and office zones would skyrocket, and all your educated citizens would take those jobs. This would force those lower level industries to all but shut down once your city grows large enough.

Citizens' education level is now bounded by the level of schooling that they've attended. Prior to Campus, simply having a university in your city would provide everybody attending school (at any level) with a high level of education. Now, this has finally been fixed such that only those citizens who attend higher levels of schooling will receive the higher levels of education. This means that if a student goes to elementary school, but doesn't attend high school (either because they get a job first, or there isn't enough capacity in your high schools), then that citizen will be capped at a low level of education and will remain eligible for those low-level factory jobs.

...

Wow, Colossal Order is really popping out these Cities: Skylines expansions in rapid succession! I feel like this is the third or fourth expansion in the last year alone! ... Hold on, let me check ...

	Expansion title	Original release
	After Dark	24 September 2015
	Snowfall	18 February 2016
	Match Day*	9 June 2016
	Natural Disasters	29 November 2016
	Mass Transit	18 May 2017
	Concerts*	17 August 2017
	Green Cities	19 October 2017
	Parklife	24 May 2018
	Industries	23 October 2018
* denotes a mini content pack, rather than full expansion.

... So, yeah; third full expansion in the last 12 months (give or take a few days). Fourth expansion in the last 14 months if you want to count the Concerts content pack. Colossal Order seems to have been following a pattern of two full expansions and a mini content pack each year since the game released. I guess that's one way to keep your game relevant. It has certainly kept me coming back every few months.

Never as robust as I would like

The problem is that the limited development time means that the content that is provided in these expansions rarely ever feels as robust or comprehensive as it should -- at least, not to me. As such, I feel like I'm getting diminishing returns from each new expansion. The amount of content that is already in the game means that each new expansion feels like relatively smaller drop of content into an already-large bucket. Each expansion feels like it gives us less to do, and has that much of a smaller impact on the overall gameplay experience.

Adding to the problem of diminishing returns: every single expansion has had some glaring omission or weakness that bothered me, and none of the later expansions have bothered to go back in and address the weaknesses and limitations of the previous expansion(s). After Dark failed to include zoneable public beaches and didn't really make the day/night cycle feel as meaningful as it should. Snowfall failed to include season cycles to go along with After Dark's day/night cycle, and completely dropped the ball with regard to mechanics like ski resorts. Natural Disasters probably felt like the most "complete" and well-rounded expansion (not to mention the most novel one), but still suffers from its content being random, and it neglected to introduce any winter-specific disasters to go along with Snowfall.

Industries follows a long-standing trend with Skylines expansions neglecting seemingly-obvious features.

Mass Transit brought the long-overdue ferry transit option, but neglected to revise cargo harbors to make cargo ship routes more practical, and didn't have any water-based city services (like a coast guard, for example) that would allow a true island economy to function without a network of bridges for freight and emergency services. Green Cities was maybe the laziest expansion, and it focused on pollution-management, but didn't bother to actually make pollution any more relevant or challenging to begin with. Lastly, Parklife granted a lot of player expression, but failed to incorporate the legacy parks into the new modular park feature and doesn't allow the camera to zoom in close enough to get a good look at your pretty decorations.

This isn't to say that all these expansions are "bad". I've liked them all (except maybe for Snowfall and Green Cities), but none of them have really wow-ed me with their content (except maybe for Natural Disasters). And the modular nature of each expansion means that it has limited-to-no impact on the core game systems, and limited-to-no interaction with the previous expansions.

The latest expansion, Industries follows suit. It promises to re-invent the way that your cities' industry functions, but kind of does it in an almost half-assed way. Much like the expansion before it, Parklife, Industries doesn't really incorporate the old legacy industry zones into the new industry mechanics. The new "Industry Area" paintbrush is virtually the same mechanic as the Park Area paintbrush from the last expansion. It isn't a replacement for the original industrial district specialization, so if feels like it's pretty much duplicating that content rather than re-inventing it.

You paint an area as an "Industrial Park", just like the parks in Parklife.

...

Parklife is perhaps the single Cities: Skylines expansion that I have most looked forward to. That is because the focus of the expansion seems to be pulled almost verbatim from my own "Great Outdoors" wishlist. I'm not going to take credit for having designed this expansion for Colossal Order, because I posted that wishlist in February, and the game is releasing in May, so unless Colossal Order is supernaturally efficient at creating expansions, there simply wasn't enough time for them to design and implement Parklife after reading that wishlist. It seems like someone in Skylines design is thinking along the same wavelength as me. But who knows? Maybe somebody did see my wishlist and incorporate some elements of my ideas into the development in progress? It's certainly one heck of a coincidence!

Much of Parklife's content seems inspired by mods.

In any case, it should seem pretty obvious that I'm pleased to see this expansion incorporate so many of my own ideas and suggestions. While Parklife still isn't going to offer the same degree of freedom and creativity that you can get from mods, having these more free-form park-creation and decorative tools should be a welcome addition for anybody who enjoys adding a little more personal flavor to their city. And honestly, is there anyone playing a city-builder who doesn't enjoy making their city look pretty?

A walk in the park

One of the strengths of Cities: Skylines has always been the way that the game utilizes its space and the natural environment. The mechanical limitations of the terraforming tools means that you rarely (if ever) have the money and terrain available to make wholesale changes to the geography of the map. Even if you have a billion dollars saved up in your city's coffers, the fact that every cubic meter of dirt that you excavate has to go somewhere, and every cubic meter of dirt that you dump has to come from somewhere, means that you can only do so much to modify the map. Starting out with a limited budget, small pool of unlocked buildings, and a relatively small plot of land means that young cities often have to work around environmental and natural obstacles, which made those obstacles part of the character of your city. Well now you can actually formally use those obstacles.

I now have a more meaningful choice of how to utilize this resource-rich mountain.

Parklife allows you to leverage these features of your landscape as part of your city-beautification plans. That mountain that is too big to level, and too steep to realistically build on, can now be turned into a massive park, complete with hiking trails, lookout points, and so forth. If that mountain also happens to have ore or oil resources under it, then now I suddenly have some meaningful choices to make on how to effectively utilize the resources. What used to be a near-obvious matter of "build some mines" actually has some viable alternatives.

Sure, you were always able to place walking paths in places like that, but the game (and the citizens of your city) never really recognized it as a place they can go for leisure and entertainment. If they didn't have to go to work on the other side of that mountain, they simply wouldn't walk those trails. No matter how beautiful you would make it, that mountain-side hiking trail was always little more than useless dead space.

Areas that used to be dead space that was impractical for construction can now be utilized.

That's no longer the case. Every last square meter of your city can now be turned into useful park space if you feel so inclined...

Didn't we just have another Cities Skylines expansion this spring or summer? Yep, we sure did. Mass Transit released only five months earlier (May 18th)! Heck, there was also another, tiny DLC pack released later in the summer as well. I didn't pick up the Concerts DLC. At $7 (more than half the price of a full DLC), I just didn't feel like it was a very good value if all it does is add the ability to make an outdoor concert venue. If the Concerts DLC had been a full-fledged expansion that focused on planning and managing city events, that might actually have been pretty cool. I actually would have been totally on board with a full expansion focused around building arenas, stadiums, convention centers, festival spaces, and so forth; then managing the traffic going into and out of them; and inviting concerts, sporting events, music festivals, trade shows, and maybe even political rallies or the Olympic games to your city. Unfortunately, the scope of Concerts is about the same as the Match Day DLC, which Colossal Order were kind enough to give away for free. Maybe I'll pick up Concerts if it goes on sale for $3 or $4.

Mass Transit, on the other hand, was a full expansion, and might very well have been the best expansion for Skylines to date. While the previous expansions were focused on adding additional flavor and customization to your city, Mass Transit actually took a stab at providing more utilitarian solutions to one of the most endemic problems that your burgeoning cities will inevitably face: traffic congestion. It was pretty successful at that mission.

Green Cities aims to solve any pollution problems your larger cities may be suffering from.

Green Cities tries to follow suit. Except instead of helping to solve your traffic woes, it offers new tools for addressing the second most significant and intractable problem your cities will ever have: pollution.

I never really had a problem with pollution to begin with

I'll admit that I never really had much of a problem with pollution in my Cities: Skylines cities to begin with. Thus, I haven't really found Green Cities to be as useful as it seems to think it should be. I usually only had a few blocks of default industry in my cities. I usually focus on lumber and farming once they become unlocked, and then go strictly with offices once those are unlocked. And even then, I rarely play a single city long enough to get it up into the millions of population. Maybe at that point, pollution is a critical issue, but for me air pollution has rarely been a problem.

Smaller cities can see some benefit from the inclusion of things like the recycling center, which is available as early as the first milestone. It can apparently replace landfills in very small cities and seems to have less of a ground pollution footprint. I'm a bit annoyed that it doesn't seem to have any visual indicator of how full the building is. It would have been nice to have animations of the building filling up with junk and processing it, but whatever. The "Recycling" policy is still its own thing (and is unlocked a couple milestones later), and I'll admit I'm not sure how (or if) the recycling center building and the recycling policy interact with one another. I guess the recycling center actually acts as garbage storage and converts some trash into consumable goods, whereas the policy only reduces the amount of garbage that the city generates. There's also an "Plastic Recycling" policy that simply improves the efficiency of the recycling center.

Recycling centers are available very early as a substitute for landfills.

Water pollution, on the other hand, is always a pretty big deal. Maps that have flowing water such as rivers are usually not a problem, but anytime I have to dump sewage into a lake (or even the ocean), it quickly becomes a cesspool. Up until now, there was virtually nothing that you could do about that...
