If your question is new vs old, then clearly new. Most are plenty exciting, fewer problems, come with warranties, support, and contemporary themes. Look at Deadpool with the family friendly audio option turned on.
If your question is LOTR vs. anything else, well clearly LOTR, as it's a great pin in its own right, and you're already saying It's a grail theme for you, and you've got a sale right in front of you.
If your question is tell me what to buy after New Years, then your waiting to see Munsters like the rest of us. But I'd still take a good look at Deadpool. Not too complicated, a fun shooter, and the Pro- right in your budget- is the way to go (vs Premium) by most accounts.
