From the back of the box:

"This box contains 450 cards:
1 each of the Common, Uncommon and Rare cards from the first release of INWO.
1 each of the three Special cards from Pyramid and The Duelist.
3 each of the nine Illuminati cards.
10 blank Groups and 10 blank Plots, to make up your own cards!

This is not just a collector's item, but a fully playable game -- that's why you get blanks and extra Illuminati cards. It includes a copy of the INWO rulebook (Version 1.1), and new rules for One With Everything play. You can divide the cards among players beforehand, or draw from "one big deck" as in the original Illuminati game.

The card backs and corners are the same as the Limited and Unlimited Editions, so you can mix cards between the sets. However, the face design of the Factory Set is new and different, featuring black frames on all cards and gold ink on the Illuminati cards."
