I've been playing Eve for about a week now. Inspired in part by the crazy stories I'd heard on the Bombcast and also by the trailers that keep popping up, I strode boldly into the expanse of player controlled space economics. I must say, it's clearly not for everyone. If you want nonstop action or really enjoy waiting in line to kill some big boss, this probably isn't the MMO for you.  
 
HOWEVER! If you are looking for an MMO where players can actually have an impact on the world, this is a clear front-runner. I should also mention that this game "does space" better than any game I've ever played (with the exception of Mass Effect perhaps).  
 
Anyway I'll be brief. I'm having a blast so far despite the lack of action. I really enjoy the feeling of working toward a goal and being a part of a player-driven world. I owe it to  Sacerdos87 for showing me the ropes and getting me started in his corporation. If you're interested in playing, I suggest you contact him on GiantBomb!
