They vary degrees but yes they do. They still function in the world he created. Do they have to be 100% Tolkien now to give him credit? What fucking straw man bullshit we pulling now? Black and white? Mate you are making goal posts, moving them, changing them into hoops, then complaining about us calling you on it.
I am not saying everyone has to love Tolkien (never said that) I am saying he has enough people that love him and his work to have a large built in audience to his work (yes in part due to the movies). Any venture/work/movie/game/whatever that is done well will make money off of his works because he wrote such a masterful world to base it all from.
You do know the movies are based on his books yes? And the games, nothing/nobody has been said that adaptations have to be 100% (in fact while talking about Rings of Power I have mentioned adaptations don't have to be and shouldn't be 100% 1 to 1, I do think you should aim to be close, like 80%, but not 1 to 1).
I never said you are talking shit because you think the books would be boring for modern readers (which in and of itself is an ass pull, if you wanted to say people are less likely to read sure, but readers of fantasy in general enjoy Tolkien), I said you are full of shit by saying Tolkien isn't a great source material WHICH ALL EVIDENCE PROVES (as dozens of games the trilogy, toys, etc) have all done very well.
Stop straw manning and get a grip that you are in this instance provably wrong.
Also if the source material is so shit for a modern audience, why would Amazon spend 250 MILLION DOLLARS JUST for the rights?
OBVIOUSLY you are an anomaly then, cause modern readers don't like Tolkien apparently.
