Good guy Amazon is saving consumers the hassle of dealing with EA's shenanigans. In light of the recent server troubles plaguing SimCity, the online retailer has removed the option to purchase the game via PC digital download. Just like the rest of us, Amazon has no clue when these issues will be fixed.
"Many customers are having issues connecting to the "SimCity" servers. EA is actively working to resolve these issues, but at this time we do not know when the issue will be fixed. Please visit https://help.ea.com/en/simcity/simcity for more information."
