Also, my grasp of American history isn't great, but the south lost this war right? And this particular battle at Gettysburg. And the Gettysburg address is fairly famous.
So, if not for the context of this being posted and then other comments here, I would assume this was a total non-event. Am I missing something? What's the supposed link between this and recent happenings with Apple store regulations and racist symbolism in the US?
edit: answering my own question, this particular cross-platform game got removed from the Apple app store as they were unwilling to edit it to remove the confederate flag from the game believing they shouldn't fall under the content ban as it was only used in historical context. It's not clear to me if it's presence is anything but a coincidence as it seems to be a well regarded game anyway.
