This idea tickled me the first time I thought of it, but I'm not the sort to do a good job at something like this. I'm wondering what the actual story told by Tolkien would look like in terms of this game.
What dice would be rolled on each turn? What cards played? Who wins what battles, where, and when?
Some things are obvious, of course, like Gandalf the Grey (Gray?) getting killed by the Balrog card in Moria. Come to think of it, it's easy for me to imagine what the fellowship's game would look like, but I'm much less familiar with what was happening elsewhere in Middle Earth. I seem to remember hearing somewhere that Lorien fell just before the ring was destroyed. Is that true?
Anyone want to try to write up a 'session report' based on this idea? Just for kicks, of course.
