This statement was made by Ubisoft's director of subscriptions, Phillipe Tremblay, who recently spoke to Gamesindustry.biz about the digital future and Ubisoft Plus specifically. Tremblay states that people eventually "got comfortable" with not owning their CD or DVD collections, and that a similar shift in attitude "needs to happen" in gamers.
Because they copy paste the gameplay, in different environments. Like "travelling to the past". I recall AC being praised for the accurate portrayal of the environments they presented. Idk if that has persisted.
I have never played the game and never will because playing a game where your dude gets into a machine to watch the memories of an antecesor of you who was a kick ass assassin and then playing as the assassin doesn't really call me, but it did to plenty people.
