The last time I played real D&D was AD&D 1st edition. Since then I've been involved in a number of other systems.

I haven't tried DDO out yet, but as I understand it, it pays the most homage to and is the most like a pen-and-paper RPG of all the MMORPGs out there, which is awesome. That's what I've always wanted when it comes to MMORPGs... the experience of playing a traditional RPG, but on a much larger scale. I'll definitely be checking it out.
