Factual inaccuracy

For games in "real-world" setting where certain facts are inaccurately stated or even completely fictitious compared to what is (or was) known.

These are usually cases where insufficient research (if any) has been done or some facts are changed for the game to be more dramatic.

Preferably the inaccuracies are explained in an article or farther defined by more specific tag.

Obviously this does not include cases covered by suspension of disbelief.
