Well, master Bungo, it would all depend on WHO wrote them. I suppose that, in a way, (Do not kill me for saying this) the History of middle earth may fall into that category. Not written by the Prof himself, but based on notes and such made by him. Undoubtedly, Chris Tolkien added in his own things, therefore we cannot really tell weather it would have been the same if John Ronald had written them.

I digress. If ol’ Chriss Tolkien wrote these ‘spin offs’, I'd have to look into them. It would depend entirely on what it was and how well written and researched it was.

If, however, you are thinking of some fat old man sitting at a computer making up some thing not unlike some of the... how shall I say this?... Less good fan fictions. Something like this;

"Sam woke up one morning and decided to go on an adventure of his own. He took Merry and pippin with him and they all went to Rivendell. There they found lots of Elf magic and flew over the misty mountains. Soon wargs attacked them and Sam had to use some of the magic Gandalf had taught him and blow up the wargs..."

Do you see where I am going? As long as it was actually followed what Tolkien had actually written I would not mind. Have a look at some of the RPGs right here on the downs, (I’m not saying they’ll be published, but that’s the kind of thinking I’d prefere If any at all.)
