Thanks alien, got them. These should keep me busy for quite a while.
Some notes after an initial viewing:
The graphic engine has changed a lot from the trailer videos. Coast has visible waves lapping on the shore. The civilization borders now look more like they did in Civ IV: there is a line of the primary Civ color, and a gradient of the secondary Civ color that spreads inward. The City-State border is a dotted line. The city bar looks a little bit different, and the Pop number and production queue have swapped sides (as hinted at in the Strategic view). Rivers look the same, but you can see that they flow downstream. The selected unit is marked with a ray of sunshine beaming down from above.
Social Policy trees: you start the game with access to Tradition, Liberty, and Honor, and other trees unlock "as you go forward in time." Some Social Policies are mutually exclusive: Freedom is incompatible with Autocracy, and Rationalism is incompatible with Piety.
Geneva is a Cultured-type city-state. Clicking on a city-state brings up a menu of options.
Stonehenge is out on the map like pyramids and chichen itza.
Fur resource appears to be foxes.
Cavalry can move an extra tile after combat.
Deserts have sand dunes.
The Glory of Rome: +25% production towards any buildings that already exist in the Capital.
The Great Warpath: Units spend only 1 Movement Point entering any tile with a Forest.
Birds flying over Fishing Boats... nice touch.
