No MMO before this one has really interested me enough to play before. I do play lots of video games though and use the computer quite a bit so I shouldn't be too noobish... Its 'just an RPG, but like bigger' is the attitude I am going in with.
In your terminology, I've been rode hard and put away wet. I've played pretty much every MMO that ever existed. Only one I haven't played is Final Fantasy, and I probably won't ever. The ones that kept my interest for more than a few weeks were LOTRO, pre-CU SWG, and EQ2. I've also played EVE off and on for over 5 years.
