PlayStation 3 remasters are apparently made to satisfy PS4 owners who never owned a PS3 console.
During an interview with Game Informer, Sony Computer Entertainment Worldwide Studios President Shuhei Yoshida talked a bit about remasters, saying that the people that currently own a PS4 but never owned a PS3 missed out on a lot of games that were “very, very popular on PS3.” Remasters allow new players to experience those games, and allow people who have already played the games to try them again in a higher resolution.
The Last of Us Remastered that we released last year was hugely popular. When we look at the number of people who did not own PS3, but do own PS4, those are people who have never tried these games that were very, very popular on PS3. Lots of people were asking for the Uncharted Collection. I’m confident that lots of people will have the chance to play Uncharted for the first time in a higher resolution, with better textures and animations. That will even attract people who played on PS3 in preparation for Uncharted 4. I’m not bothered by people who complain when we talk about remasters. There are always those people on the internet.
A Sony representative later clarified that around 40 percent of the 20.2 million PS4 owners never had a PS3 (8.08 million people). While a number of remasters have already been released, there are more coming up, including Uncharted: The Nathan Drake Collection and God of War III.
