“Boy, this game is really green and brown”

Oh, I’m so sorry the post-apocalyptic nuclear hellscape that is the “Captial Wasteland” of Fallout 3 isn’t more colorful or pretty enough for you. I’m sorry that after that millions of people died and human civilization was vaporized—and while survivors live in a constant state of fear and starvation—you have to look at some brown textures and green-tinted buildings.
How about this: Instead of complaining about Fallout 3’s drab environments and dreary landscape, you embrace it and become immersed in the dead world Bethesda has crafted.
