You're running through the streets of Paris. The year is 1789 and you've just killed a guy with your bare hands. The question is, do you care if the graffiti you just sprinted past is historically accurate? Ubisoft does.

The video game giant's latest installment of its biggest franchise, Assassin's Creed Unity, takes place in Paris during the French Revolution and developers went to great lengths to not only make sure its multi-player mode was firing on all cylinders and the story of protagonist Arno is engaging, but that the sights, sounds and action all around the city were as close to the real thing as possible.
