Richard Leadbetter of Digital Foundry writes “Some might say it was a game that was simply too ambitious for its intended platform. In 2014, Ubisoft’s spectacular Assassin’s Creed Unity pushed back technological boundaries in a range of directions. Its depiction of Revolutionary Paris was dense in detail, packed with hundreds of residents on-screen at any given point, in a city that didn’t just increase detail outdoors – but introduced highly detailed interiors too. Combined with big advances in character rendering and an astonishing global illumination system that still looks incredible today, Unity had all the makings of a masterpiece. The problem was, it didn’t run very well at all.”
