So, what cool features have you found from the game that are not made explicit anywhere? I'll start: there _is_ a list of units in the game! You just need to click a unit name at the bottom right corner: vignette3.wikia.nocookie.net/civilization/images/a/a8/Unit_list_screenshot_(Civ6).jpg/revision/latest?cb=20161102172934
Another cool thing is that you can now rotate the camera around the cities, units and terrain! Just hold the alt-key while clicking and dragging your mouse. The only downside is that once you let go of the alt key, the view resets, so it's difficult to take screenshots while the view is rotated.
