3. Fallout 3
This one is particularly sweet because, as many fans have noted, Borderlands takes a bit of inspiration from Fallout 3. Miss Moxxi's Heart Breaker, your reward for completing the mission Safe And Sound in her favor, bears the phrase, "I Don't Want To Set The World On Fire", lines from Fallout 3's iconic opening song, performed by The Inks Spots. Other references include the Bandit shotgun Thre Dog, inscribed with the words "Because one barrel ain't enough, and two is too few.", a reference to Fallout 3's post apocalyptic DJ, Three Dog. Maya can also unlock a skin called Vault Dweller, which resembles the classic suit worn by inhabitants of the many vaults dotting the Wasteland.
