Personally I'm most thrilled by the idea of creating your own missions! Storytelling in game that goes beyond RPing? Awesome!
The Day Job thing sounds cool as well.
So what are you all most pysched about?
Also, darkrose and I created a pair of stalkers and let me just say that a stalker duo can wreck a hell of a lot of damage, particularly when their players are sitting next to one another and easily and quickly can work out the plan of attack.
