AI Variation in AI speech.
AI Don't declare war if the AI has no cities.
AI AI sometimes considers sneak attacks (declaring war) against cities
        that it thinks may be weak or likely to be undefended.
AI Reduced weighting of building improvements that only contribute to a
        Civilization's Power.
AI Tweaked some AI weights for Industrial era technologies.
AI AI was missing an opportunity to build Settlers, as city size grew from
        1 to 2.
RULES Fog of war: enemy units can now only be seen when near to your cities
        or units. Satellites technology eliminates fog of war.
RULES Air units can now perform Reconnaissance, to reveal fog of war for that
        turn.
RULES New units: Galleons, Ironclads, Dreadnoughts, Battleships. These can
        accompany units attacking by sea, and defend against incoming invading
        units.

        Of Passage agreement.

        their territory.

RULES Sailing requires Ocean near a city to research; Iron Working requires
        Hills near a city to research; The Wheel requires Forest near a city to
        research.

RULES New improvement: Market.
RULES Captured cities of size 1 don't start resistance (unless already
        resisting). Give player the option of using troops to deal with
        resistance, for cities of size less than 10. This reduces the
        population, and reduces the resistance.

        automated units where they spend ages moving around railways in
