I'm kinda new to the game and wanted to get some clarification. Ok I know Bread = Food = faster population growth Hammers = Production = faster unit training/buildings Are coins and moneybags are the same thing. i.e. 5 coins = 1 moneybag? So do coins & moneybags = commerce, but what does commerce equal, research? Is there an icon for gold? I get confused between moneybags and gold coins.
