For performance reasons, I’d like to install full games on the local hard drive and run ‘em from there. Or, if possible, stream shit from a cloud-based streaming service.
Actually, when I getting the PS4, I’d like to get rid of discs altogether. But I dunno. You see, Shuhei Yoshida, President of Sony’s Worldwide Studios for SCE, did confirm the option to fully install from discs (although the corresponding disc ought to be present in the tray for verification purpose).
So if I buy games on the PSN Store, I wouldn’t need any discs, but then again, the best prices are usually not found there, but rather on random disc sales.
