One google pieces of paper alone would mass somewhere around - eep - that's a high number. OK, you know how heavy our galaxy is? 2x10^56 times heavier than that. That ruleset would collapse spacetime (locally if not throughout the entire Universe) and bring about an end to everything.
And they say roleplaying isn't evil...
A 100,000 page document, on the other hand, printed on A4 paper with hardcovers, would probably only weigh as much as the average gaming group (excluding dice) and, stacked in one pile, be about twenty feet high. That's a project I could really get behind (well, only if there was villainy afoot and I needed a place to hide, but hey).
I've heard it said that there are 10^87 particles in the Universe. This really puts a crimp in plans to produce these larger projects; I anticipate that advances in quantum mechanics will be necessary to create the continuums necessary to produce the mass/energy to build such reality-dwarfing projects. Just think, you could be building entire universes simply to serve as generators for the project.
Isn't science grand?
