How big is Just Cause 3 XXL Bundle? (In GB)

[GoonGoblin]

I got Just Cause 4 for free on the Epic Games store, but it just didnt feel the same as Just Cause 3? I was wondering the size of the game before I get it. (Yes I know it says on the store page, but usually when I go to download a game, it says it takes up more space than it actually does. E.g. it said CS:GO was 20 GB, but when I was downloading it, I went to Library>Downloads, and it said 11 GB.)

Steam recommends 60gb free space on the drive.

Alright, I started downloading it, and it says its only 46 GB. Why does it say that?
