No-one is talking about that, why did you even think that was possibly related to the thread?
It's partially tangential, but still related to the topic. I just can't abide the idea of franchise fiction. Sometimes novels will successfully make the jump to another medium; I can't think of a single instance of a work in another medium successfully making the jump to novels.
He says he doesn't want to at first, he is reluctant in both the book and the film.
It's been a while since I've read the books, but from what I remember he doesn't debate the issue all that long. Sure, as soon as Gandalf breaks the spell, he doesn't jump up and shout WAR ON ISENGARD AND MORDOR NOW, but neither do I remember him resisting very hard the call to honor the old treaties and aid Gondor. I'd have to re-read the books to find out for sure.
And the Silmarillion and the Children of Hurin are unknown for a reason (that reason being they are hard to read). And the in-game TES books are pretty good.
The Silmarillion and the Children of Hurin are very easy reading. They aren't in verse, or anything, and many of the stories in the Silmarillion are fairly short. The earliest parts of the books tend to read like mythology, and are quite short.
As for the in-game TES books, sure, they're good in terms of being in-game books, but they're a far cry from being novels.
