I thought this would be a let down; a total screw up of Tolkien's lore. I was wrong! It's fun, and true to the books!
One thing that stood out from all else (especially coming from Vanguard) is that, for me, this game was rock solid. No bugs, no crashes, nothing. The game scales VERY well graphically and should be playable on any PC 2-3 years old. One thing however, there are queues, so If you create a player on a busy server you're gonna wait. On launch day only 3 servers had a queue and my wait on each was less that 5 min, if that. There are currently 11 servers (if I recall correctly) so there are many to choose from that shouldn't be overpopulated. When you launch the game the launcher app recommends servers for you that aren't overly popluated. I came from WoW over a year ago to start playing Vanguard (no MMO is as frustrating and painful at $14.99/month) and I have to say that LOTRO is a nice breath of fresh air. Yes, it somewhat favors WoW but to me that's a bit of a compliment because I consider WoW to be a very well made MMO as well. Hopefully however LOTRO won't become the timesink of life itself that WoW turned into. If LOTRO truly retains it's solo-ability and balances it with the nice fellowship (group) system, then I believe Turbine won't alienate it's player base based on who has the most time on their hands like Blizzard did.
So if you're looking for a fun MMO and are a fan of the Tolkien books then this is your ride.
