I am a huge fan of the Tolkien books but never considered a table top game other than War of the Ring and Battle of Five Armies. WotR is a great game. However, I am is very intrigued by this miniatures game.
I am considering shifting off 40K to LotR SBG for a couple of reasons. I can get the Battles of Pelennor Fields for a decent price. And my understanding is the Rohan, Warriors of the Dead, and Mordor armies will require much less to build out to 800 pt forces than the current requirements for 2 40K forces.
