Do you know of any MMORPG where you can become an über-mighty tyrant and torture everyone else like a total bastard?
I'd love it if everyone started chasing after me and I always succeeded at escaping and creating new havoc somewhere, and so on.

I'd like to feel how it is to be a hated dark lord whom everyone wants dead.

Being the Tolkien freak I am, I could compare myself to Sauron (or perhaps Morgoth) - you know, the kind of dangerous demon that troubles the world, bla-bla-bla.
I'd like to control such a character in a video game.
