LotRO isn't a bad choice. If nothing else the game if free to play and lose nothing but time.I was considering buying it until I realized I have the same problem with LotR that I do with Dragonlance in that I'm not really sure what I'd want to do with a setting that has a definitive and specific tale it revolves around. Weirdly, I don't have this problem with Star Wars, probably because I've read so many books and played so many games that aren't Skywalker focused. And I guess that's really my answer to the dilemma. I've been thinking of trying out Lord of the Rings Online, so maybe I'll immerse myself in the world that way and see if anything sticks.
Do keep in mind that game runs more or less concurrently with Lord of the Rings. You will for example run through areas right before or right after the Fellowship does. The quest line that takes place in Bree for example expands on what Aragorn is doing before Frodo leaves The Shire, and you have some fun with Aragorn as an NPC and some ranger allies.
