I kinda found this forum after doing a search for "the continuing story of middle earth" or some such on Google, so you might be right about the RPG thing... once I've settled in anyway!
I've always found it curious that so many people have written in "The style of Tolkien" or "In remembrance of" or "Inspired by"..... etc....
And yet as far as I know, no-one has ever attempted to continue the stories of characters beyond the ring stories. This might be ignorance on my part? As in its happened and I haven’t noticed, or it could be that someone’s protecting the rights like nothing you've ever seen? Or perhaps that no-one dares coss Tolkien was so damn good they just don't think it'd be right?
I'd be interested to hear peoples thought on that one..... though I'm guessing its been discussed before if I trawl the forum for long enough....
I've no intention of trying it myself until much more comfortable I'd have to say

I'd feel a fraud!
