It so would!!! And you are welcome
It's an old topic, but in case anyone still care about it I can actually confirm that Xbox version and Win 10 version of the game have shared achievements and saves! So it's basically the same version, you even can play Win10 version with a gamepad.
I hadn't played a lot of city builder games before, but when Cities became available via Xbox Game Pass I decided to give the game a chance. And I liked it so much! I spent huge amount of time playing the game on my Xbox, but was quite disappointed that it's not a Play Anywhere title. Because from time to time I don't have access to my Xbox and can play only on PC.
Once, I noticed that game's title in my xbox profile changed from "Xbox One Edition" to "Windows 10 Edition". After that I was digging through the Internet and found this topic, it was another disappointment - if Community Manager says it doesn't support save sharing, it shouldn't, right?
But now Cities is on sale in windows 10 store and I finally decided to buy the game there, maybe just to start a new city. And I was so happy that it downloaded saves from the cloud and I got my city from Xbox on PC!
So it's the same game on Xbox and Win10, too bad it's not a Play Anywhere title and you have to get a two copies. But it's defenetly a game where cross-saves do their best.
Thanks for following up. It'd be great if they could. *wink, wink*
If you still wants to play on PC buy a copy while it's on sale, don't miss a chance
