this is why you buy ps4
You still have to install the game from the disk. Getting a PS4 puts you at no other advantage in this scenario.
Also OP, yes, games these days do take up that much space. Especially battlefield with all of those delicious raw gunfire sounds. CoD Ghosts even took about 40 gigs of space if I recall correctly.
Harddrive space isnt a rare thing these days. AAA Game Devs will use more than 8 gigabytes of data for a game now, because the person downloading them should at the very least have 500 free gigabytes to spare.
