Civ3 must have quotes just like SMAC did. It will add so much in terms of atmosphere. I think historical quotes should be used as much as possible. It would be so cool to have quotes from Ceasar, Napoleon, Churchill, Lenine etc. Obviously, this is not possible everywhere. It would be fine if Firaxis invented a few quotes, they certainly did a fine job on smac. They could use quotes from famous novels too. I guess the only rule should that the quote should be as fun as possible and make the tech "come alive" for the player!
Specifics, let's see:
Flight: quote from Wright brothers, maybe.
Communism: quote from Lenine or Marx.
Democracy: how about the famous quote from Churchill about it being bad but better than anything else.
Rocketry: quote from Von Braun (inventor of V2)
Philosophy: quote from socrates, maybe.
Code of laws: maybe ten commandments quote.
Nuclear: quote from Oppenheimer "destroyer of worlds".
Space flight: "One small step for man, one big step for mankind."

Well, I am sure Firaxis will find much cooler quotes than these.

Communism: "From each, according to his ability; to each, according to his need." - Karl Marx, The Communist Manifesto

Nationalism: "I regret that I have but one life to give for my country." - Nathan Hale

Computers: "Computers are useless. They can only give you answers." - Pablo Picasso

Tactics: "If I determine the enemy's disposition of forces while I have no perceptible form, I can concentrate my forces while the enemy is fragmented. The pinnacle of military deployment approaches the formless: if it is formless, then even the deepest spy cannot discern it nor the wise make plans against it." -Sun Tzu, The Art of War

Philosophy: "I cannot teach anybody anything, I can only make them think." - Socrates

Democracy: "Many forms of Government have been tried, and will be tried in this world of sin and woe. No one pretends that democracy is perfect or all-wise. Indeed, it has been said that democracy is the worst form of Government except all those others that have been tried from time to time." - Winston Churchill

Space Flight: "The Earth is the cradle of the mind, but one cannot stay in the
cradle forever." -Konstantin Tsiolkovsky

You guys talkning about "quotes with advances".

quote: Space flight: "One small step for man, one big step for mankind."

That's one small step for (a) man, one giant leap for mankind.

Alas at his big moment he got his line wrong.

Some specifics:

Philosophy: Descartes, "I think, therefore I am"

Computers: "640K ought to be enough for anybody" - Bill Gates

"'Sir' didn't mean anything, Kelly knew. When in doubt a marine would call a lightpole 'Sir'."

- John Kelly
(Tom Clancy, Without Remorse)

And I remember thinking, as soon as I played my first SMAC game, how cool it would be to implement those sort of quotes for Civ 2, using voice actors to read pertinent quotations from the great books of history.

I like the idea, it adds some feel to SMAC, the sense that you're 'doing something', a sense of accomplishment part way through the game.
