It's revealed that the game will take up approximately 28.12 gigabytes. That's not too bad given that some games out there, such as
GTA V on PC, will take up like 60gb worth of space. Essentially
Fallout 4 is only half the size of Rockstar's HD rendition of their open-world action title.
The revelation of the game size probably comes as a surprise to many, given that
Fallout 4 is expected to be an absolutely massive game. However, Bethesda doesn't appear to be pouring a whole lot of their attention into the graphics so much as they are the gameplay content. Texture resolutions, geometry density and even detailed light rendering maps can sometimes take up a heck of a lot of memory (especially if the light maps are pre-baked). But in this case it looks like Bethesda worked some compression magic for
Fallout 4 to keep the game as lean and as mean as possible.
That level of efficiency is always appreciated.
Now some people might assume that the game only being 28gb means it's tiny or that Bethesda gimped on the content. It's easy to assume that when you compare it to a beast like
GTA V that clocks in at 60gb, but keep in mind that
Fallout 4 doesn't have a lot of needless civilian dialogue to take up more than 10gb alone and it doesn't have three different protagonists with several gigabytes worth of speech data.
There's a lot of bloat attached to
GTA V, where-as in the case of
Fallout 4 a lot of the game's weight in hard drive space comes from all of the different interactive entities in the game. There are a ton of objects littered throughout the game world and many of them can be used for crafting and upgrading your equipment and character, and there aren't any vehicles that you have to worry about where they take up so much memory due to sounds, damage data, liveries and physics. So when you actually look at it there's a plausible reason why
Fallout 4 is a lot smaller than
GTA V in regards to space and it doesn't by any stretch of the imagination mean that it's a smaller game in terms of gameplay content or interactivity.
