I don't need any swastikas inside or outside the game. If you can't imagine that you're on a german WW2 sub without a swastika on your flag than that doesn't say much for your imaginative capabilities. (Don't want to offend anybody, didn't read all of the post
but still ...)
The Nazis have turned a whole lot of things into mess that nobody can use now without creating the association with holocaust and mass murder, and the poor swastika is now only one of the things we can't anymore
