Having just yesterday played a game with those 2 armies (I commanded dijit's evil horde against Torben with his fancy-pant elves ), I have ordered the rulebook just now.
I plan to start playing with @Duregar using our respective LotR collections (Duregar has a substantial amount of Dwarves from before they went failcast), and then parallel to that build a force in 15 mm to play with the rest of Denmark (and hoping to also influence others to use existing collections, be it Warhamster, Kings of War, or whatever fantasy minis they might own).
Sounds good, it's quite something that most of us in Denmark are playing it in 15mm.
I think the rules with their simple mechanics but tactical depth offer a lot.
