Buy both, clean them up and sell the one you don't like after a month. No way you can possibly lose money if you're in it at the right price. Both are very in demand games.
Not a LOTR fan, The game was fun but I found myself avoiding it because of long ball times. I couldn't take the rings of men call out anymore either. Scared stiff is still here. However I agree with the others where it's better in a larger collection.
