No, they didn't. You don't have to ask the copyright holders to quote a movie, since copyright is designed mainly to protect the commercial viability of entire works. If you couldn't quote passages from something without permission, it would be impossible, for example, to critique something if the author didn't want you to.

Hence, you can quote, say, Monty Python without ever asking them; if you reproduce an entire skit rather than a few lines you might get in trouble (since the skits are the product, in that instance), but Bethesda would have a hell of a time persuading a judge that a CoD game featuring the phrase "War Has Changed" would somehow prevent them selling Fallout games.
