Out of all 50 games on this list, Borderlands represents the larger idea of a video game "world" better than any other. While the basic setting of the game is a dull wasteland populated with insane convicts, Pandora has more than enough character, personality and twisted history to actually have us want to revisit the planet again in the sequel - rather than moving out into the universe at large.

From the moment Cage the Elephant's song "Ain't No Rest For the Wicked" starts up in the intro sequence, we're given a view of everything that we need to know about this world: no life is sacred, and your heroes are made up of unsympathetic mercenaries. Bringing up visions of post-apocalyptic films such as Mad Max, Pandora is a cruel place, but a distinctly humorous one as well. With characters like the claptraps, creatures like the Rakk Hive, locales like Zombie Island, and one undeniably interesting character after another, the world of Borderlands continues to draw us in and have us looting for hours on end.
