Back at launch, GameLuster recommended the title, with reviewer Axel saying: "Ghost of Tsushima gives players all the romance and bloodshed of being a samurai, while moving them to meditate on the price one pays to fight against an occupying force, all within one of the most gorgeously rendered environments ever seen on a PlayStation 4."
