I think Destiny 2 gave my PS4 another lease on life.
When I read that D2 was gonna require 67+GB, I ordered a 2TB SHDD immediately. Of course, I was mistaken with the size requirements, but my HDD had been giving me trouble (had to re-install everything once cause it got corrupted) so a new HDD was in the cards.
I also had my PS4 cleaned in anticipation of the long hours playing D2. I saw photos of the inside and it was amazing how much dust and cat hair was inside. I honestly don't know how it never turned itself off because of the heat. Also had the thermal paste changed because I know that's a problem with launch units.
Now, my PS4 is silent and I have plenty of disc space. Already downloaded TESO, which I had deleted because it was taking up a huge chunk of space (it's up to 70GB now).
