I can't wait to see what their next big expansion is. You can tell they have a lot of ideas still. I want a carnival. Though the zoo looks a but light on animals or action.
Also, I wish they'd make it so every population step (Village to Town to City to etc to etc) had its own day and night music. I love the music in SimCity SNES and how it changed with each population boom. All of them were basically rearrangements of the first one but they were awesome. Skylines still just has one song. I'm almost tempted to turn the music off and just play an extended loop of SimCity SNES music.
And while we're at it, seasons. We all want it. Hopefully the next update is Cities: Skylines Four Seasons or something. Bright grass and pink flowers and rain in spring, vibrant green grass in summer, brown grass and colorful trees in fall and bare trees and white snow covered ground and rooftops in winter. Plus the winter could bring problems like snowstorms that cause roads to be closed off for a day or a few fake hours. Snowplows and salt domes would be the next big service. They'd only work in the winter, but when they do, man you'll be ready. Plus in the fall and winter, the beachfront attractions would close. I mean you just know they gotta be thinking about this already. There's too many good ideas for seasons. Just make it so seasons are an option from city creation in case someone doesn't want them. Or they want to pretend their city is really far south.
Oh, and I still hate that I can't switch back to my desktop from the game (Command+Tab or Alt+Tab for you Windows people) if it's in fullscreen. I get locked to the game and nothing else. And quickly changing the resolution to windowed just fucks up the alignment of underground stuff like pipes and tunnels. Of course now that I said this, I tested it and it's working again. Maybe it's bugged and flakey. Or it's because I'm still only on the menu. Maybe it only works while at the main menu?
