I had an amazing time as Hailey the ghoul. I was more active than any of my regnants, and rather than being bored or stuck with casual RP, I wound up getting into a bunch of plot, to the point where Shavalyoth actually wrote me into the metaplot so I had a very major personal stake in it. The plot affected everyone on grid and what I was doing mattered, whether people knew about it or not.
What's more, in addition to being one of the plottiest people, I was able to provide all kinds of tangible benefits to my regnants when I wasn't trying to save the world, both off screen with rolls, and on with RP. I wheeled and dealed to make sure they got this job offer or that boon. I was able to go out and play politics with the vampires even though I wasn't Empowered to speak, and in almost every case I was treated with ooc respect by all the players I dealt with. I can count on one hand the number of times I was relegated to being furniture, and I was averaging ten scenes a week.
