When you load up SimCity you will now get an option to choose single player.
These saving options speak for themselves. Where is the load option you ask? You have to exit back to main menu and select ‘play’ (not resume)
The only less-awesome part is the confusing stuff that happens in your documents folder, this is where it saves your games:Not really clear which game is what! I’m sure the modding community will work on making this easier for us.
