Fishing for Cities Skylines expansion ideas: holidays?

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
	Concerts*	17 August 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!
