First thing to do is build alot of cities then put your taxes to 0 then use turns until your happiness is 100 percent then keep your taxes at 50 percent from now on and your happiness will be 100 and stay that way.This way you get money alot faster and the game is alot less boring.takes less time to get to the fun attacking/researching part.(+ so new people will stay and fight for us!)
