You could have been improving luxuries, building mines or constructing roads during those three turns. If you're on a difficulty where you can consistently build the Pyramids, pretty much any strategy is sustainable. Move up a couple of difficulty levels, and you will get punished for inefficiently building Farms.
Never did I say I was neglecting my special resources, roads, or expansion. I always improve specials first. Just because I said I build farms, doesnt mean I blindly spam them everywhere. C'mon. I said I farm river tiles, plains, and the infrequent desert hill with fresh water. I also build trading posts in grasslands and flood plains, mines on bald hills, lumbermills in forests. And great people buildings in empty desert tiles when I feel like it (or plains hills in the case of the manufactury). It's nothing new; I'm not reinventing the wheel here.
Food that is generated by working a tile is less efficient than food that is gifted by a Maritime, because you have to spend Happiness to get the food. That's a killer in the early game, when Happiness is the primary constraint on your empire.
I find this inconsequential in the grand scheme of things.
Yes, but if you're working tiles to generate food, you need more citizens to generate the same level of Hammer/Gold output as a player using Maritimes. Therefore, food generated by working tiles is Happiness inefficient.
This is a valid argument. However, I still prefer supplying my own food and keeping my gold to purchase buildings or units rather than paying off a city state.
