The "back" button in the 'pedia does not work. (Not that the 'pedia is much good anyway:for example, it tells you what city-states are but not how to interact with them) What's the point of Bronze Working when there is no copper ? Cotton is a new resource, but pigs, clams, crabs, corn, rice, stone (and copper) are absent. This despite many posters' hopes for more types of resource, not less. No World Builder in-game. Is there one elsewhere ?
