Call it installation or call it caching, but the bottom line is that you will have to save large chunks of PlayStation 4 games to the system's hard drive. It's not an option. It's mandatory on Sony's next-gen system. Today, at a stylish waterfront hotel in New York City that's been taken over by Sony for all things PS4, the system's lead architect, Mark Cerny, explained just how these requirements work.
Physical gaming ftw! No need to buy a new HDD for quite some time for me. Ill just delete the install data when im done with a certain game...then if i want to play it again i will just re install it and start playing while it is doing so. Nice.
