The Lonely Mountain: Lair of Smaug the Dragon (Boardgame based on The Hobbit) I so wish I would've kept my old game books and Dragon magazines. Alas, they were stolen by Gypsies in the Midwest, US. True story. Moving on... This guy's apparently sitting on a lot of old (and high-priced) Middle-Earth gaming stuff. http://amzn.to/2sBcWDw
Huh... that actually looks a lot like the floor-plan design they had in the movie, except on a smaller scale than the film. I'd have to crack open my book to see if Tolkien described it with walk-ways and spans and pillars and such, but its late and thats not happening!
ICE games. Their Middle Earth system was a variation on Rolemaster. I never did the Middle Earth stuff, but, I did use the Rolemaster system. It's definitely d100 percentile dice based.
You're right, @Seagrim. I never had this board game, but we did play the Rolemaster system. Good times.
