I didn't see anyone running a Middle-earth rpg, past or present. However, I did manage to snag from the dealer's room a very nice copy of the slip-cased edition of The One Ring: Adventures over the Edge of the Wild from Cubicle 7 (my sole purchase at the con).
Tayna actually ran three game-sessions at the con, not two. Friday was the Country Dawgs game using the rules for Dawg: The Roleplaying Game from Kenzer & Co. Saturday evening was a Firefly game (based on the Joss Whedon TV series) and a Doctor Who game, both using D20 Modern & D20 Future game mechanics. All three had decent turn-outs; she had to turn away players for the Saturday sessions.
