hi,
try <system drive>:\Users\<your name>\AppData\Local\Colossal Order\Cities_Skylines\Saves
That's where Steam version stores them. These two games are very different. MS turned this game into their one of their new Universal Windows Platform Games designed to run on any version of windows. i.e. phone, xbox, pc, etc. Everything is encrypted, hidden, and broken up into several folders and probably tied into the registry. it is a total mess. This thing is worse than the Games For Windows Live platform they tried. Looks like Steam is safe for now. lol
Since the setup is similar to the Xbox edition I wonder if similar savegame issues are plaguing this as well?
I imagine so, I don't see it be too much different than Xbox One as it now runs Windows 10 as well. But mine keeps dropping the internet all of the time for some reason. Is there a Discussion for this game on the MS store or somewhere? MS seems to have eliminated any kind of support for the game everywhere. I don't blame them, they don't want everyone talking bad about this new crappy platform. All I want is access to my saved data. They couldn't be bothered to at least give us access to own own work.
