Here we are in December, and Colossal Order has yet to announce a second expansion for Cities Skylines since releasing the Campus expansion back in May. This will be the first year since the game's release that Colossal Order will only be releasing a single expansion. They have released some mini content packs, so there has been some new Skylines content -- just not a full-blown expansion.

	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

	Green Cities	19 October 2017
	Parklife	24 May 2018
	Industries	23 October 2018
	Campus	19 May 2019
* denotes a mini content pack, rather than full expansion.

But that doesn't mean that Colossal Order has abandoned the game. In fact, they've been very active on Twitter asking for people's opinions on what kind of new content we'd like to see. Most recently, they posted a tweet asking if we'd like to see buildings with seasonal holiday decorations (such as Christmas and Halloween). Earlier in the year, they also asked if we'd like to see mechanics for car wrecks or urban decay (among other propositions). Even though these ideas seem to have been positively received on Twitter, and lots of follow-up ideas were presented by commenters (including myself), no new expansion has been announced.

Colossal Order's Twitter account has apparently been fishing for new content ideas.

Though I wouldn't be surprised if Colossal Order announces an expansion before I'm able to finish writing and publish this blog post...

Personally, I've liked all the ideas that they've suggested, in principle. As you may know, I have some gripes with how Colossal Order has handled its expansions for Cities Skylines, so I would hope that any possible future expansion would try to resolve those lingering issues. So let's go through the ideas that Colossal Order has pitched on Twitter and see if they would be worthy of an expansion pack!

...

Some of the suggestions from my first wishlist have actually been implemented in Cities: Skylines. Naming roads, and adding directional traffic overlays were recently added in the Mass Transit expansion, and the previous Snowfall expansion incorporated some of my ideas for seasonal cycles (minus the part where the seasons actually cycle from one to another). There's still a lot of items from that wishlist that haven't been implemented. I also have come up with some new ideas for things I'd like to see in further expansions (or maybe a sequel?).

Taking the best ideas from its competitors

Even though Cities: Skylines is, by far, my favorite (and probably the objective best) city-building / city-simulation game of the past decade, there are still some features and ideas from the inferior games that I really like. In my first wishlist, I already talked about how much I liked the modular building mechanic of SimCity (2013).

I won't go into too much detail of why I liked that concept (even though the actual implementation was a little weak) because I invite you to read the original post. Suffice it to say, I liked the idea of certain pieces of city infrastructure (such as power plants, schools, universities, police stations, airports, government buildings, etc.) actually growing along with the city. Being able to upgrade an existing building to add additional functionality, additional capacity, or to specialize it in some way, was (in my opinion) a much more interesting and engaging process than simply plopping another copy of the same building every so often, or adjusting a global budget slider, simply to meet increasing demand.

I still think SimCity had the right idea with its modular buildings.

In that first wishlist, I also briefly mentioned the Cities XL series. There isn't much in XL (or XXL) that is done as well (or better) than what is offered in either SimCity (2013) or Cities: Skylines, but I did neglect one idea that I think was probably the most clever, interesting, and fun part of the XL series of games: the ability to "fill" an area with "decoration". Put simply, Cities XL allows the player to fill any unoccupied area of the map (that is at least partially enclosed by roads) with one of several different types of decorative landscaping.

Landscaping options include a grassy park area with trees, an open-air "flea market" with kiosks and street vendors, various plazas / courtyards, and even a makeshift construction site. These decorations aren't functionally different (the flea market doesn't produce any commerce or jobs, for example), but each decorative area applies a very small environmental beautification effect that increases happiness and land value for adjacent homes or businesses.

Decorative areas in Cities XL allows you to fill-in irregular shapes with city-beautification projects.

From a more aesthetic standpoint, Cities XL's decorative areas allow the player to make very efficient use of space, to fill any empty dead space, and to create your own custom parks and plazas that conform to whatever shapes the outlining roads happen to be. Want a park in the middle of a large roundabout? Want a plaza space at the point of a 45-degree (or narrower) intersection? XL allows you to do such things without having to go into an asset-editor to make a custom ploppable.

Despite having muuuuuch better tools for creating curved and angled roads, Skylines doesn't really have any equivalent to these decorative features from XL that allow us to fill-in gaps left by our pretty, rounded or angled roads...

I've been playing the somewhat-underwhelming After Dark expansion for Cities: Skylines. I love Skylines, but there are a lot of elements of the game that I wish would change, and a few things that I would like to see added. I hope (and expect) that Colossal Order will continue to support the game for many years to come with new DLC and expansions, and this blog will outline some of the features, mechanics, and items that I would like to see changed or added to the game.

It should go without saying that, since this is a PC game (with a built-in asset creator), many (if not all) of the following suggestions might already be implemented in one or more mods. I haven't played much with mods in this game yet, so I don't know what might be available. In any case, there's no reason why ideas already implemented in mods can't also be turned into formal game systems by the developers.

The one thing I miss from SimCity (2013): Modular buildings

As much as I love Cities: Skylines, and as much as I think it blows the SimCity reboot out of the water, there is one mechanic of SimCity that I absolutely love, and that occasionally makes me want to go back to SimCity: building upgrades. It's a bit ironic that SimCity, with its ridiculously limited city size, is the game that allows you to add additional components to existing buildings that makes them take up more physical space; yet, Skylines, with its expandable city plots, uses only prefab buildings of set sizes. So the game that puts a premium on real estate availability encourages you to leave empty space around certain buildings. I guess it makes sense. SimCity's limited size means you can't afford to build whole new buildings and must make due with what you have. Skylines allows you much more space to just keep copy-pasting the same schools and garbage dumps every few blocks.

Having to build new schools every four or five blocks can become tedious in Skylines, especially when the city starts to cross into being a metropolis. I like that the game requires that you build more infrastructure in order to keep up with population growth, but I wish that you could push the existing buildings a bit further before having to build whole new ones...
