I am greatly enjoying it. It plays similar enough to WoW/EQ2 that you will be instantly familiar to it's play style. The combat is much slower than the button mashing in WoW and that has taken some people awhile to get used to, but it fits better with the RVR ( Realm vs Realm ) system.
If you are looking for a PVE game though, I would advise not getting it just for that. The PVE is fun, especially the Public Quests, but the PVE element is just "good" but nothing to get really excited about. Where the game really shines is in it's RVR aspect. The game was made with RVR from the ground up, and it shows. Open world battles can be massive. I am only lvl 24 ( out of 40 ) and we had a running 3 hour battle last night with over 200 people fighting at keeps, holding actions at bridges, retreats and regrouping to attack again, desperate fighting on the walls of keeps, sallys from inside the keep, to rushing to massacre a besieging force from behind. It was the definition of the word EPIC. It was literally the most fun I had ever had in my history of gaming.
The game is broken up into 4 tiers, and only levels of that tier can fight in those zones. If a high level comes into one of the lower level RVR zones, they are turned into a chicken with 1 hit point. So, high levels can't come in and wipe out the low levels. Also, if you are a level 1 and go into an RVR zone or a Scenario ( WoW Battleground ) in your tier, it buffs you up to level 8 while in the zone so you can be somewhat competitive.
So, it really is a GREAT game, if you like RVR. The PVE is a fun distraction for when you get bored of the RVR for a while, or need a change of pace but the game is made for RVR action and it truly shines in that aspect.
Hope my review helps.
