9 Video Game Plotlines You Didn't Realise Were Based On True Stories

9. Nioh

The game: Thanks to a smart ad campaign highlighting the similarities between Team Ninja's action adventure and From Software's gothic fantasy Dark Souls, fans of the latter series looking for another fix, following its conclusion, elevated Nioh from curio status to hugely anticipated.

Forced into a trip to Japan to retrieve a precious possession stolen from him by a lackey of the English monarchy, set protagonist William soon finds himself in the thick of Feudal Japan, one that's besieged on all fronts by an invading force of demonic Yōkai.

The inspiration: Much of Nioh is fictional. For starters, demons don't exist, thank the stars, nor does the fancy magical substance, Amrita, central to Nioh's conflict.

William, on the other hand, was a very real person and did emigrate to Japan, though not to retrieve a magical Guardian Spirit. The real William Adams was one of few to survive the arduous expedition to the Far East and the first Englishman to do so.

Not only that, but he was one of, if not the first 'Western Samurai' in history and would become a close friend of Tokugawa Ieyasu, otherwise known as the man responsible for a unified Japan and the birth of the Edo period.
