Fallout 4 Day One Patch is only 500MB on PS4, total game size is 41GB

Fallout 4 will be released on November 10, 2015 for the PC, Xbox One and PlayStation. Before we start the game, a 500MB Day-One-Patch will be downloaded.
As a surprise, “Fallout 4” will supply with a day-one patch. This is with its 500MB which does not seem particularly large, at least as regards to the present day.

Also that the Apocalyptic RPG game “Fallout 4” calls for a day-one patch to version 1.01. This information is initially valid first only in respect of PlayStation 4, but on the PC and especially on the Xbox One, the whole thing is very likely to move in similar dimensions.
Fallout 4 game total comes to a size of about 41 GB. Unfortunately, Bethesda has provided no patch notes for the first update to the grid. Fallout 4 is going to release on November 10, 2015 for the PC, Xbox One and PlayStation 4.
Fallout 4 takes place 200 years after a nuclear war which is set in a post-apocalyptic Boston where the character emerges from an underground bunker known as a Vault.
For the successor to Fallout: New Vegas, so far, hardly any information are known.
