Does anyone else have the slightest idea what a "fubar" Mt Doom mold for WotR CE/AE is?
Yes. Fubar's a user on BGG who made custom Mount Doom models that fit on the collector's edition oversized maps for War of the Ring. They add a great deal of "pop" to the look of the game, as Doom is such a focus point of the game.
