The Matrix or WoW?

An interesting article is up over at the New York Times entitled Our Lives, Controlled from Some Guy's Couch.

Basically, some big-brain has created a mathematical formula which indicates that there's a fairly high certainty that we're all a computer simulation. Some free-running form of Second Life or Spore in order to watch how we evolve and react and grow.

Of course that begs the question, is the person who created our simulation - in a simulation of his own? And that question can be extrapolated up and down (when you consider that it's expected for us to have computers powerful enough to perform such simulations by the middle of this century).

So, which MMORPG would you rather be playing in?
