First of all, most of the sword and sorcery genre is derivative of Tolkein, so why not just use the original Although they did only license the Lord of the Rings material, not the Silmarillion so some die hard fans do miss the extra depth that would provide.
It is a fairly adult crowd, particularly on my server(Silverlode). They aimed for a niche of players and I think they hit it pretty well. There were a few of the PowerG@m4r type around at the beginning, but they blew through the whole thing in a couple months, did the big bad guy(a dragon at the time). There was nothing left for them to do, and they were done with the game and moved on, leaving a more casual friendly crowd. They are trying to keep a base of players as they slowly and carefully create the whole Lord of the rings realm, which is a schedule for 2014 or so I have heard. So far we are just up to Rivendell, with Moria and Lorien comming in a big expansion in Nov.
They have done a failry good job of class balancing without twinking or super powering. For example there was a time after the beginning where Guardians(Tankiest Tanks) were feeling left out, and unneeded. Champs and Captains(hybrid tanks) were able to tank things fine, and with their extra abilities they were prefered. Rather than a bunch of class adjustments they started tuning the newer areas so that a real tank was enough of a help over a hybrid tank, that there was demand again. They have done a good job of giving each class valuable skills unique abilities that aresometimes required, without leaving anybody out or getting to arbitrary about forcing it.
There is a PVP element but it isn’t huge. I’d say about 70% of the people never go PVP, 20% do sometimes, and 10% are primarily PVP, but I might be a bit skewed based on my kin.
It is a few zones where people take their normal hero characters and fight other toons that are evil(orc, spiders) that only exist in the PVP(or freep vs creep) zones. They pretty much flat out said that they arn’t making PVP a priority, because its not thier vision.
Along with levels there are deeds. Deeds are accomplishments such as visting certain places, or killing x number of mob. Each has ranks, and depending on class you usually focus on the deeds to rank in the stats you are going to need. It can get pretty grindy to be honest. But a level 50 with no deeds done, is seriously weaker than a fully deeded 50 of the same class.
The carfting system takes a good bit of time, but most everybody who plays gets into it, even though there really isn’t much money to be made these days. The best stuff is about equal between top-crafted crits, and raid gear, and zone sets(these take a bit of repetition in high end zones to get, but not as much time per session as a true raid, just more sessions. Crafting is more about a sence of accomplishment and having fun, rather than making stuff no one else can. Gathering mats for crafting the high levels is a huge grind however.
It is a lot of fun, though I am taking a break to try Warhammer before Moria comes out, but when it does I am back there full time. Like I said it is purposly designed to be paced for adults and casuals to have fun for a long time. And the graphics are great, and lag hasn’t been a problem for me for months, while Warhammer has horrible bad nastly unplayable lag on my same system.
Mostly they have done, in my opinion, a great job of making the Player actions and plot seem relevant to the activity of the Lord of the Rings story, without stepping on existing things, like throwing someone into the fellowship as unexplained badass. That was my biggest worry before it came out. Tolkein was kind enough to leave open ended things around the main story that the players can have fun doing.
