If he'd only been able to use a word processor even, we might have seen it all decked out in language as compelling as we know he could write, because he was at least as prolific as Terry, but soooooooo flaming slooow - how Christopher Tolkien stayed sane piecing together all those hundreds of thousands, if not millions of pieces of longhand draft manuscript and scrawled notes I'll never know - just as well he occasionally got a typist in, or actually used a machine himself, else we'd never have got what we have in The Hobbit and LotR and the other books published in his lifetime.
This is what I meant when I was saying in another thread about how Tolkien's from another era, or even a whole world in reality now so comparisons to contemporary fantasy writers are hard to make in some respects.
