The standard game difficulty was too simple. I would fend off an early attack and then be able to go to their city and wipe out the entire civ without ANY resistance. So im playing on Emperor level which is one under the hardest and need some tips. So I think i need to build new cities to raise more gold, right? Does distance from the capital decrease gold or happiness. How does number of cities reduce happiness. Any other tips for settling new cities, keeping gold and happiness up and expanding borders would be greatly appreciated.
