Conditional on this universe being a simulation, the universe doing the stimulating has laws vastly different from our own. For example, it might contain more than 3 extended-spacial dimensions, or bear a similar relation to our universe as our universe does to second life. 99.999%

I disagree with this one more than any other comment by far. Have you looked into Tegmark level 4 cosmology? It's really important to take into account concepts like measure and the utility functions of likely simulating agents when reasoning about this kind of thing. Upvoted.

My reasoning is that it would take more then a universe's worth of computronium to completely stimulate a comprable universe.

One could argue that they're taking shortcuts with, e.g., the statistics of bulk matter, but I think we'd notice the edge cases caused by something like that.
