We also used to play Lord of the Rings Trivial Pursuit with my other siblings. We couldn't let my sister go first because once it was her turn she answered every single question correct, continuing her turn until she won without us even getting to answer a single question.

It was a mix of movie and book trivia, but even if it had been all deep cut Silmarillion stuff it would have played out the same way. I can now never forget about the Uruk-hai Lurtz, invented for the first movie.
