Because a) it used to be until 8 years ago when you simply could not get any USK ('Entertainment Software Self-Regulation Body') age rating for any game depicting such symbols.And b) it still can be. Swastikas in video games can be legal today, but not in general. In essence, the regulations for video games have been adapted to the long-standing practices applied to films and similar media: It's allowed only within the context of a socially appropriate, historically or artistically justified depiction. It is probably easier for the publisher to omit it entirely if this context might not be clear enough in the game.
Interesting! Thanks for the clarification, Lusche. Is there some pre-authorization requirement, or does one just do it and argue about it later?- oldman
