LOTRO is a good time. I've been in since closed beta. Sure, it's not perfect but its fitting my play style very well.
Graphics are really nice and quests are the best I've ever seen in an MMO.
DDO was a huge disappointment for me but Turbine appears to be doing a much better job with LOTRO so far. I am waiting to see what is added/fixed in the first big content patch coming in the next month. That will tell a lot in my opinion about Turbine's capabilities and LOTRO's future.
