Slow PSN + that stupid copying mechanism = this is what you get (and people scratch their head whenever I say how bad console/experience PS4 is)... Supposedly the copying procedure is required due to HDD, but PC and XB1 don't have it despite the same HDD being used, so I guess it has something to do with the file system being used in PS4. Cerny even addressed the issue during his Road to PS5 speech, but I don't know, we can already mount SSD inside the PS4 and the copying is still there, forced by the system, just faster, so the question is if PS5 will get rid of it or will it still be there, just much faster.
As for the game size itself, it is indeed ridiculous, are there some hidden 8K textures or what?? It's a common knowledge some data on the consoles are duplicated even 20-40x, but come the fuck on... I wish there was a system where you could download or even just buy the parts that interest you (SP/MP/Coop), rumors say PS5 will indeed allow for something like that, and I hope this is true, so others will take notice and follow suit.
