[2019] Should I get this?

Game isn't that expensive anymore, and the Season Pass is on sale. I had a few questions. I'd be playing this solo like Conan Exiles.

1) How big is the total install size? Game looks like 16gb on the PS Store, plus 35gb or so for the latest update. But can't find the DLC download sizes.

2) How big is the save file? Saw stuff where it was listed as 20gb or so.
