I had a LOTR and i think it's a really great pin, a masterpiece. But i sold it because games are too long for my tastes.
I had a TWD Pro, trade it 9 months ago, and bought a second one 3 days ago. I think this one will stay.
Lotr is epic and easily one of the best pins of all time but if you like kick ass game like IM, BSD, you'll love TWD.
Try to keep the LOTR if you have a good one, it's a must have.
