Do you buy more than you can chew or take one game at a time?

This is exactly the reason why I decided to leave my PS4 HDD at 500 Gigs and not upgrade to a bigger one. If I have 500 Gigs of games in my backlog, I need to play those games before I buy new ones. When I finish one I back up the game save and erase that sucker off of there so fast it would make your head spin.
