For those that have Starcraft 2, a few of us have been playing a lot of tower defense recently. If this appeals to you, catch us on bnet or in mumble in the evenings.
I'm enjoying it. What I like about it is how the customizability is so vast for character skills. It boils down to your character choosing three classes and picking and choosing bits and pieces of each of those to make his character into what he wants (at least 2 by max level, at most 3). Now, it's both more simple and more complicated then that, but that's the general idea.
The rift concept is also really cool, where basically it goes from a normal day to little mini world events occurring where complete strangers are getting in raids together to fight these invasions, forcing teamwork.
So far, I've enjoyed the content, I've started running some of the high level dungeons. I never played WoW so I can't really compare them, but I know at least that the graphics in this are less...cartoony? Also it's obviously a newer game with a better looking world. It seems there are lots of WoW players coming over, but then, I think just about every has played WoW at some point. I do know the game servers are constantly full. (Not too full to get into).
The most positive thing I can say about it, is this game has the most responsive and involved Dev team I've ever seen in a game. Excellent communication, response time and transparency.
I can get more indepth with the game details if anyone is interested.
