Yes, LOTR has one of the most difficult to reach Wizard Modes in the history of pinball: Valinor. I can understand some criticism of that. I know that I will never see it. So I forget that it is even there.
And that's easy to do, since there are a TON of other achievements to go after. Having owned my LOTR for 4-5 months, 2 nights ago I beat FOTR Multi-ball for the first time! "YOU SHALL NOT PASS"!
There are two more MB modes to beat as well. I've beat TTT a few times, but never RotK.
Destroying the Ring is always a great goal. Achievable but not easy. Love how the machine goes apeshit, similar to the Vacation Jackpot on WH20.
Bottom line: LOTR is a great pin, and there is a reason that it is ranked so high both here at Pinside and at IPDB.
