It's complete torture, this stuff.
So it's a 140MB download
But that will be totaled with 30-40+ GB when you factor in ALL the downloads you ever made for that title. This is what the PS4 will count, rather than the measly 140MB.
You'll probably have to clear an extra 10GB of space to make up 80GB at least.
It's a joke, frankly.
Hmm, I don't think it even that - I have about 40GB free right now and am attempting FFXV Judgment Disc (only 13.5GB) and still it won't work. That title is its own self-contained download so it can't be over the limit surely.
And don't call me Shirley.
