I was in a similar situation as you and have the same games, woz, TH and LOTR. If I was to get rid of one it would be LOTR, as I find it a repetitive. Most times I play it I destroy the ring. I have reached valinor twice, and not much left to shoot for. It is a great flowing game and has really satisfying shots. Woz on the other hand is random and there is always a different way to play. If you are keeping the hobbit I would go with the Woz, as LOTR is too similar to TH in my opinion.
