LOTRO is pretty fun. It's a LOT like WoW, but with better graphics and more to do excluding PvP. PvE seems just as well done as WoW, if not better. The Monster Play (PvP) in it is pretty cool from what I've seen too. I haven't had a chance to play that part much. It's got some great co-op play and it's not all based around freebie arena epics. I'd give it a shot if you haven't already. I'm playing with some friends on Brandywine. Also, one of the coolest things is that you can learn a musical instrument skill in the game and then actually play it by hitting each note. You can bind individual notes to keys and jam away. I swear I heard someone playing Metallica on a lute the other day.
It's only $10 to buy and that comes with a free month. There is also a free trial for like 14 days, but it doesn't come with the highest resolution textures in that download. You can find them to download though or just get the install off the DVDs.
