I'm a sucker for anything sustainable. Seriously, don't say the words "vertical farming" anywhere in my vicinity unless you want a documentary-length lecture on the subject. That's why I might have to jump back into Cities: Skylines for the new Green Cities expansion.
For $12.99 you can outfit your metropolis with electric car charging stations, desalination plants and glass pyramids paved over with greenery for sucking all that nasty CO2 out of the air. You can even take things a bit more authoritarian by enacting combustion engine bans, but I'd prefer that my citizens come around to the green way of thinking without heavy-handed government sanctions. Check out the trailer below for more info, and grab the DLC here.
