Despite the horrible press the game has received since launch, it seems many consumers will either not research a game they are picking up or are so die hard they will buy anything a company puts out, even if it has a number of issues and is practically unplayable the week of launch.
Today EA announced that SimCity has managed to sell over 1.1 million copies. This makes it the fastest selling SimCity so far and roughly 50% of these are for the digital version of the game. Of course when the game requires an online connection and functioning servers, any version may as well be digital.
