I have been playing LOTRO for about 6 months and after just a month, I was hooked enough to buy a lifetime subscription! I can really see myself playing this until servers go down. I also got my wife hooked on it and she now wants me to get her a lifetime!
Anyways, I used to be very against MMO's in many respects especially for the monthly fee and the time that they can consume. Now, with getting the lifetime for $200, equal to 4 new PC Games, as well as having my wife enjoy playing with me, I am completley content with playing this game for years to come.
I have tried a few othe MMO's but could never see myself paying including WoW. LOTRO changed that whole perception for me. Turbine is great at releasing new content and they have already released plenty of new areas to explore at no charge! I don't think any MMO can compete with that. I find the questing to be interesting and relevant, something I have sorely missed from RPG's such as Baldur's Gate.
I think that LOTRO is perfect for anyone who has never gotten into an MMO especially if you like setting. The graphics really bring the game to life especially with the scencery. It is a very immersive experience and there are several things that set the game apart from WoW which make it my type of game. Again, I feel the community to be much more mature.
