Looking back at Fallout 3, Game Director Todd Howard says Fallout 4's graphics won't be as "depressing".
In a panel presentation at E3, GameSpot reported that Howard talked about the importance of graphics and memory when it comes to immersion.
"If we make a world that has, not just more details, but more dynamic details that we can keep track of and stream in and load quicker, all of that suspends your disbelief that this is a real world. The graphics matter, they do matter in suspending your disbelief."
When asked about the stark difference between Fallout 3's drab wasteland and the more vibrant environment seemingly present in Fallout 4, he said "Looking back at Fallout 3, there is a sameness to the environment. It can be, if you're playing the game for an eight-hour stretch, a little depressing."
It's not all sunshine and rainbows in Fallout 4 though. He did emphasise that the area where the bomb fell might not be so colourful - obviously.
