Literacy is described as giving a 25 point credit to Diplomacy, while the rulebook gives that bonus to Democracy (I'm thinking the quick chart is correct.)

Enlightment is described as giving Theocracy a credit, which the rulebook doesn't.

Fundamentalism is described as requiring Deism, which the rulebook has Mythology instead (while Mythology in the QuickChart agrees with the rulebook)

Monotheism is described as requiring Mythology, while the rulebook has Deism (while Deism in the QuickChart agrees with the rulebook.)

Naval Warfare requires its damage to first come from the coasts, if possible.

Theology is described to decrease I&H by three, however the rulebook describes it as deceasing by one.

Library matches the rulebook regarding its effects on Regression. However, Fundamentalism implies something different than the rulebook when it describes what happens when Library and Fundamentalism are both present.

Trade Routes is described as 1:1 and occuring at any time (which is different from the rulebook.)
